pjproject_bundled: Fix for Solaris builds. Do not undef s_addr.

The authors of PJProject undef s_addr because of some issue in Microsoft
Windows. However in Oracle Solaris, s_addr is not a structure member, but
defined to map to the real structure member.

+Subject: [PATCH 1/2] [RFC] pjproject: Fix for Solaris builds. Do not undef
+ s_addr.
+
+pjproject, in order to solve build problems on Windows [1], undefines s_addr in
+one of it's headers that is included in res_rtp_asterisk.c. On Solaris s_addr is
+not a structure member, but defined to map to the real strucuture member,
+therefore when building on Solaris it's possible to get build errors like:
+
+    [CC] res_rtp_asterisk.c -> res_rtp_asterisk.o
+    In file included from /export/home/admin/asterisk-11-svn/include/asterisk/stun.h:29,
+                     from res_rtp_asterisk.c:51:
+    /export/home/admin/asterisk-11-svn/include/asterisk/network.h: In function `inaddrcmp':
+    /export/home/admin/asterisk-11-svn/include/asterisk/network.h:92: error: structure has no member named `s_addr'
+    /export/home/admin/asterisk-11-svn/include/asterisk/network.h:92: error: structure has no member named `s_addr'

+    res_rtp_asterisk.c:706: warning: dereferencing type-punned pointer will break strict-aliasing rules
+    res_rtp_asterisk.c:710: warning: dereferencing type-punned pointer will break strict-aliasing rules
+    res_rtp_asterisk.c: In function `rtp_add_candidates_to_ice':
+    res_rtp_asterisk.c:1085: error: structure has no member named `s_addr'
+    make[2]: *** [res_rtp_asterisk.o] Error 1
+    make[1]: *** [res] Error 2
+    make[1]: Leaving directory `/export/home/admin/asterisk-11-svn'
+    gmake: *** [_cleantest_all] Error 2
+
+Unfortunately, in order to make this work, I also had to make sure pjproject
+only used the typdef pj_in_addr and not the struct pj_in_addr so that when
+building Asterisk I could "typedef struct in_addr pj_in_addr". It's possible
+then that the library and users of those interfaces in Asterisk have a different
+idea about the type of the argument. While on the surface it looks like they are
+all 32 bit big endian values.
