ae0e919135 Microoptimization of sendfile(2) usage under FreeBSD.
FreeBSD kernel checks headers/trailers pointer against NULL, not
corresponding count.  Passing NULL if there are no headers/trailers
helps to avoid unneeded work in kernel, as well as unexpected 0 bytes
GIO in traces.

13717da19e Unlock of shared memory zones on process crash.
If process exited abnormally while holding lock on some shared memory zone -
unlock it.  It may be not safe thing to do (as crash with lock held may
result in corrupted shared memory structure, and other processes will
subsequently crash while trying to access shared data), therefore complain
loudly if unlock succeeds.

91ecc8f43c Added shmtx interface to forcibly unlock mutexes.
It is currently used from master process on abnormal worker termination to
unlock accept mutex (unlocking of accept mutex was broken in 1.0.2).  It is
expected to be used in the future to unlock other mutexes as well.

Shared mutex code was rewritten to make this possible in a safe way, i.e.
with a check if lock was actually held by the exited process.  We again use
pid to lock mutex, and use separate atomic variable for a count of processes
waiting in sem_wait().

07bb4ed971 Introduction of simple ngx_write_stderr() instead of ngx_log_stderr()
for output of ./configure options, etc., since ngx_log_stderr() output
length is limited by 2048 characters defined as NGX_MAX_ERROR_STR.

ce61ff9c45 Fixed another return in unix ngx_write_chain_to_file().
Previous patch missed special case for one iovec, it needs total bytes
written to be returned as well.

aecb2eda13 Fixed unix ngx_write_chain_to_file() to return total bytes written.
Previously result of last iteration's writev() was returned.  This was
unnoticed as return value was only used if chain contained only one or
two buffers.

4134b48b68 Fixing Linux AIO syscalls return value handling:
syscall(2) uses usual libc convention, it returns -1 on error and
sets errno. Obsolete _syscall(2) returns negative value of error.

Thanks to Hagai Avrahami.

59efbc4bcb In Mac OS X Lion, Apple deprecated the use of the system OpenSSL library
in favour of their CommonCrypto library.  This change adds a work-around
that allows nginx to still be built on Lion with OpenSSL.

4f65a05d18 Bugfix: open_file_cache lost is_directio flag.
On file retest open_file_cache lost is_directio if file wasn't changed.
This caused unaligned operations under Linux to fail with EINVAL.
It wasn't noticeable with AIO though, as errors wasn't properly logged.

566dfe0c7f SIGWINCH/NOACCEPT signal is disabled now in non-daemon mode.
Non-daemon mode is currently used by supervisord, daemontools and so on
or during debugging. The NOACCEPT signal is only used for online upgrade
which is not supported when nginx is run under supervisord, etc.,
so this change should not break existant setups.

ec8186c733 Move SO_ACCEPTFILTER and TCP_DEFER_ACCEPT checks into configure.
NetBSD 5.0+ has SO_ACCEPTFILTER support merged from FreeBSD, and having
accept filter check in FreeBSD-specific ngx_freebsd_config.h prevents it
from being used on NetBSD.  Therefore move the check into configure (and
do the same for Linux-specific TCP_DEFER_ACCEPT, just to be in line).

ef1f33b0db Use more precise stat.st_blocks to account cache size on Unix

9b67ca0e41 Fix a bug introduced in r2032: After a child process has read a terminate
message from a channel, the process tries to read the channel again.
The kernel (at least FreeBSD) may preempt the process and sends a SIGIO
signal to a master process. The master process sends a new terminate message,
the kernel switches again to the the child process, and the child process
reads the messages instead of an EAGAIN error. And this may repeat over
and over. Being that the child process can not exit the cycle and test
the termination flag set by the message handler.

The fix disallow the master process to send a new terminate message on
SIGIO signal reception. It may send the message only on SIGALARM signal.
