This is one of those patches which will either make matters far
simpler after the bugs shake out, or will get reverted pretty quick
once we realize that it is a stupid idea.
We now post-process the config.h file into a new event-config.h file,
whose macros are prefixed with _EVENT_ and which is thus safe for
headers to include. Using this, we can define replacement timeval
manipulation functions in evutil.h, and use them uniformly through our
code. We can also detect which headers are needful in event.h, and
include them as required.
This is also the perfect time to remove the long-deprecated acconfig.h
file, so that autoheader no longer warns.
Should resolve the following issues:
[ 1826530 ] Header files should have access to autoconf output.
[ 1826545 ] acconfig.h is deprecated.
[ 1826564 ] On some platforms, event.h can't be included alone.

Resolve issue 1826588: make event_base_free() succeed even if there are pending non-INTERNAL events still in the base. This can leak memory and fds if used injudiciously, but at least it no longer crashes.
svn:r490
Remove rtsig method, as discussed in July. It hasn't compiled for quite a while, and nobody has seemed to miss it much. Please let us know if this was a bad call. [Tracker issue 1826539].

Quick hack to make evhttp.h build when there is no TAILQ to be found. Based on patch from Paul Fisher. We could perhaps do this more elegantly, but it _does_ need to be done.
svn:r475
Correct the pointer manipulation in fake_getaddrinfo(), and do the right thing for fake_getaddrinfo(NULL,&ai). Based on a patch by Lubmir Marinov, hacked until the unit tests passed on Linux with #undef HAVE_GETADDRINFO.
svn:r459
Apply patch from Trond Norbye with recommendations from Magne Mahre and Hannah Schroeter: make autogen.sh work on systems where /bin/sh is not bash.
svn:r444
More DNS standard correctness changes: we preserve the CD flag,not the TC flag on responses. When we get a nonstandard query, we should say "NOTIMPL" rather than ignoring it.
svn:r428
Changes to http.c: Add a Date header on replies if there is none already set. Also, include time.h unconditionally to be sure that struct tm is declared: every platform has time.h; the conditional should have been for sys/time.h.
