Changes made here:
1) MULTIPATH_NUM will never be 0. If user specifies --enable-multipath=0
then this translates to MULTIPATH_NUM being set to 64 inside of the build
system.
2) Move MULTIPATH_NUM from a Makefile construct to a config.h construct.
3) Allowed MULTIPATH_NUM to be a number > 99 but < 1000

bgp_btoa was abandoned at some point in time in the past.
This commit gets it to compile and to be added to /usr/bin.
At this point in time no work has done for 'correctness' of execution

In cases where a distribution has compiled zebra with a MULTIPATH_NUM
that is less than what the user is setting the maximum-paths in bgp,
warn them that some of the nexthops will not make it into zebra and
by extension the kernel for routing. The command is still accepted.
dell-s6000-02(config)# router bgp 100
dell-s6000-02(config-router)# maximum-paths 3
% Warning: maximum-paths set to 3 is greater than 2 that zebra is compiled to support
dell-s6000-02(config-router)# maximum-paths ibgp 44
% Warning: maximum-paths set to 44 is greater than 2 that zebra is compiled to support
dell-s6000-02(config-router)#

* Remove the old change from '08 to add in PIE arguments at automake level.
Versions of libtool since then know how to deal with -fpie and do the right
thing according to whether its building shared or executable objects.
So just pass '-fpie' as CFLAG and let libtool do its thing.

This allows enabling -Werror in a consistent way. Note that this is
different from just specifiying it in CFLAGS, since that would either
break configure tests (if done on ./configure), or would override
configure's CFLAGS (if done on make).
Using --enable-werror instead provides a new WERROR variable that is
additionally used during make with a consistent set of warning flags.
The tests/ directory is exempt. (Rationale being, better to have more
tests than pedantically complain about them.)

INCLUDES in configure.ac was not used at all, and INCLUDES in
Makefile.am is supposed to be AM_CPPFLAGS these days.
Reduces warnings spewed during bootstrap/autoreconf.

The correct method to link to NetSNMP is to use net-snmp-config (which
is like pkg-config). Explicit link to libcrypto is also dropped
(NetSNMP libs are linked to libcrypto, no need to link Quagga to
it). Moreover, @SNMP_INCLUDES@ is dropped because useless. Due to a
bug in configure.ac, it was properly populated.

Some .h files in lib/ are autogenerated. The search path should
include the build directory and the source directory. They usually
match but sometimes, they may be different. For example:
$ mkdir build
$ cd build
$ ../configure
$ make

* configure.ac: sys/conf.h depends on sys/param.h, at least on
FBSD 6.2.
(bug #363) Should check for in_pktinfo for IRDP
2006-05-27 Paul Jakma <paul.jakma@sun.com>
* configure.ac: General cleanup of header and type checks, introducing
an internal define, QUAGGA_INCLUDES, to build up a list of
stuff to include so as to avoid 'present but cant be compiled'
warnings.
Misc additional checks of things missing according to autoscan.
Add LIBM, for bgpd's use of libm, so as to avoid burdening
LIBS, and all the binaries, with libm linkage.
Remove the bad practice of using m4 changequote(), just
quote the []'s in the case statements properly.
This should fix bugs 162, 303 and 178.
* */*.{c,h}: Update all HAVE_* to the standard autoconf namespaced
HAVE_* defines. I.e. HAVE_SA_LEN -> HAVE_STRUCT_SOCKADDR_SA_LEN,
* bgpd/Makefile.am: Add LIBM to bgpd's LDADD, for pow().

* Makefile.am: bgpd shouldn't list libgp's sources as its own.
Use LDADD.
* bgp_aspath.h:
(struct assegment) New struct, abstract representation of a
list of AS_PATH segments and the contained ASNs.
(struct aspath) Remove the raw-data related
fields, reference the abstract struct assegment instead.
Remove several other computed fields, it's just a
headache to maintain them and they're cheap to compute from
struct assegment.
(aspath_parse) parse a stream, not a pointer to raw data.
(aspath_count_{hops,confeds,size}) helpers to access
information formerly directly contained in struct aspath.
(aspath_snmp_pathseg) Helper for SNMP, BGP MIB wants
to be able to output hex representation of raw data.
* bgp_aspath.c: (general) partial-rewrite. Store aspath data
as an abstract singly-linked list of abstract segments,
rather than storing the raw data, and parsing it each and
every time. Remove several count/size fields which are cheap
to compute from the abstract segment structure.
(global) Include stream.h, needed for aspath_parse, and
others. Couple of helper macros added.
(struct assegment_header) Just the header, and only the
header.
(assegment_data_{new,free}) convenience functions for
AS_SEG_DATA allocation, the dynamic, per-segment array of
ASNs.
(assegment_{new,free,free_all,dup,dup_all}) convenience
functions for creating struct assegments. The _all forms will
follow the entire chain of segments from the given segment.
(assegment_prepend_asns) new function, prepend an ASN N times
to segment.
(assegment_append_asns) Append a list (array) of ASNs to
segment.
(int_cmp) convenience function for the aspath hash.
(assegment_normalise) new function. Normalise the given
segment chain to meet expectations of Quagga, and to
eliminate differing raw representations of the same paths.
Merge 'runs' of SEQUENCEs into one segment as our internal
segment is not limited by the protocol AS_PATH segment
length. Sort ASNs in SETs.
(aspath_new) Take void argument to quell warnings. Use the
assegment convenience functions.
(assegment_count_{asns,confeds,hops}) new functions to
compute at runtime values previously held in struct aspath.
(aspath_size) ditto.
(aspath_make_str_count) rewritten to stringify new
representation, and to be slightly easier to understand
hopefully.
(aspath_str_update) convenience function, update the aspath
str. Should investigate removing maintained string from
struct aspath, just run-time compute it, as per other fields.
It's just a maintenance headache, would save noticeable
amount of RAM with possibly not much extra run-time cost.
(aspath_dup) use the assegment dup functions.
(aspath_hash_alloc) Take void * argument to satisfy gcc. Use
the proper helper functions to dup data.
(assegments_parse) new function. parse raw AS_PATH data into
struct assegments. Normalise and return the head of the list.
(aspath_parse) Parse a stream, not pointer to raw data and
use assegments_parse to do it.
(assegment_data_put) Write out a single segment data in protocol
form to stream.
(assegment_header_put) ditto but for segment header.
(aspath_put) new function. As per previous but for an entire
struct aspath.
(aspath_snmp_pathseg) wrapper around aspath_put for
bgp_snmp.c. Uses a static buffer sadly.
(aspath_aggregate_as_set_add) rewritten to use assegments.
(aspath_aggregate) ditto
(aspath_{firstas,loop,private_as}_check) ditto
(aspath_{merge,prepend,add_one_as}) ditto
(aspath_cmp_left{_confed}) ditto
(aspath_delete_confed_seq) ditto, plus fixed to properly
delete all leading confed segments.
(aspath_as_add) Just use assegment_append_asns.
(aspath_segment_add) updated to use assegments.
(enum as_token) Add values for confeds
(aspath_gettoken) Add support for confeds
(aspath_str2aspath) ditto
(aspath_key_make) updated to use as_segments. Also, add
segment type into the hash value as appropriate.
(aspath_cmp) updated to use as_segments.
(aspath_print) don't segfault on NULL argument.
* bgp_attr.c: (bgp_attr_aspath) aspath_parse wants the stream
now. No need for manual forwarding of stream.
(bgp_packet_attribute) empty aspath is now denoted by NULL
segment field, length is gone.
Use aspath_size() to determine size.
(bgp_attr_init) Fix declaration, explicitely specify void
arg.
(bgp_dump_routes_attr) Use aspath_size() to determine size.
* bgp_route.c: (bgp_info_cmp) use the aspath_count_* functions.
(bgp_rib_withdraw) remove unused variable. Use
aspath_count_hops.
* bgp_snmp.c: (bgp4PathAttrTable) raw data is gone, use
aspath_snmp_pathseg to get the representation.

* */Makefile.am: Use ../dir/libfoo.la, rather than "-L../dir
-lfoo", to avoid linking against installed libraries from a
previous version.
* {lib,ospfd,ospfclient}/Makefile.am: explicitly define the shared
library version number to be 0.0
* configure.ac: remove spurious , so extract.pl is chmod'd +x.
* HACKING: explain shared library versioning rules

libzebra and libospfapiclient are now built shared, and linked shared
with the daemons. This reduces the memory needed when running
multiple daemons; each daemon is at least 150k smaller. Static
libraries are still built, and libtool should use them on platforms
which don't have shared libaries. As with autoconf, the user of a
distribution does not need libtool; one just needs that to build from
CVS.
libospf.a is still a non-shared library, and still installed, not
because that makese sense, but because I don't understand why it is
the way it is now.
Note that the tree was tagged 'libtool-before' just before this commit.

This is needed to support (cleanly) NetBSD pkgsrc, which requires that
example config files go in $(prefix)/share/examples/pkgname, rather
than in $(prefix)/etc/pkgname.
