correctly - logically complete that now by removing MLINKS from base;
authors need only to ensure there is an entry in NAME for any function/
util being added. MLINKS will still work, and remain for perl to ease
upgrades;

Adopt the more concise fcntl(n, F_GETFL) over fcntl(n, F_GETFL, 0)
where it is obvious further investigation will not yield and
even better way.

tcpbench (at a minimum) relies on the old behavior of changes all happening
after all event handlers run. in particular, it resets the event for the
listening socket *before* calling accept(), when it is still readable.
kevent then (correctly) says it is readable on the next go through the loop.
silly, subtle, and stupid.

of deferring until the dispatch loop. kqueue support for various types
of files and filesystems has been historically incomplete, and kevent
handles this condition by returning an error. the libevent dispatch
loop has no way to recover from this error and fails catastrophically,
bringing down the entire process because one file went bad.
now, instead of all that happending, event_add will return an error. the
application can choose to handle or ignore this error, but at least the
band will play on.

- Avoid deadlock when activating signals. Fixes bug 3048812.
Based on patch by Nicholas Marriott.
The deadlock was ultimately fixed in a different way (by disabling
reinit - see event.c r1.25). Add it now for consistency but without
the Windows compatibility code. Convert the fnctl() calls to
SOCK_CLOEXEC | SOCK_NONBLOCK to simplify the code.

- For this fix, we need to make sure that passing too-large inputs to
the evbuffer functions can't make us do bad things with the heap.
On top of that do:
- Update libevent version to 1.4.15-stable.
- Use SIZE_MAX from limits.h instead of a private define.
- Do not declare 'size_t need' twice to avoid a compiler warning.

switch fprintf(stderr) over to event_warn() on malloc failure. fix
up an errant newline in an existing event_warn while there.
originally i just wanted to delete the fprintf
diff from nicm@ who is away from a keyboard right now so cant commit

evbuffer_foo functions do. reyk, nicm, jmc, and schwarze seem to
support a manpage as a reasonable solution to this problem.
im putting this in a separate manpage because i find they get too
cumbersome when they get too big. ingo agrees (and suggests even
this might be too big).
the file is evbuffer_new.3 rather than evbuffer.3 because we document
functions.

Separate the API of evutil from libevent and do not include evutil.h
from event.h automatically. A version bump is not necessary as the
library itself does not change.
Bulk ports build done by landry@ had no fallout.

CIRCLEQ_* is deprecated and not called in the tree. The other queue types
have *_END macros which were added for symmetry with CIRCLEQ_END. They are
defined as NULL. There's no reason to keep the other *_END macro calls.
