Log message:
One more try.  event.h gets installed and used by other programs so
we can't use config.h in it.  Instead use the substitution framework
which was already in place for making some other SunOS changes.

Log message:
SunOS-5.9 doesn't have stdint.h.  There is already a configure test for this
so use the results.

Log message:
Update to libevent-1.3d. ChangeLog is not available but from the homepage:

libevent-1.3d:
Bug fixes in the HTTP layer.

libevent-1.3c:
Small bug and portability fixes.

Worth mentioning is that patch-ab and patch-ac were applied upstream.
As usual with libevent, this breaks the ABI due to .so naming, so a
small revbump sweep will be needed.

Log message:
Fix build on AIX: event.c needs time.h to get CLOCK_REALTIME and
the select implementation needs sys/select.h. The latter should be
detected by autoconf, but can break e.g. older DragonFly.

Log message:
Detect built-in libevent version.
Need for net/spreadload (PR 36348).

Log message:
Use c99 uint* types rather than u_int* on HPUX.

Log message:
Update to libevent-1.3b.
1.3b:
    * Fixes when using signals in multi-threaded applications from Scott Lamb.
    * Other small bug fixes.
1.3a:
    * Small bug and performances fixes to evhttp layer.
1.3:
    * DNS Server from Adam Langley and Nick Mathewson
    * Chunked transfer encoding for HTTP/1.1 from Dug Song.
    * DNS DDoS fix; bug report from Jon Oberheide.
    * Various small improvements.

Log message:
improvements to last:

- configure script already has provision for different compiler inline
  directives, just not every file was using it.
- u_intXX_t types need to be fixed in installed event.h too.

Log message:
make this build on Solaris with sunpro.
