Note that "ctxt->loadsubset = 1" previously used isn't really correct as
ctxt->loadsubset is a bitfield now. The use of xmlCtxtUseOptions() with
XML_PARSE_DTDLOAD is believed to be a better way to do the same thing.

POSIX doesn't require it to be defined, and Debian GNU/Hurd doesn't define
it. Note that if there is no MAX_PATH defined we have to use realpath()
with NULL argument and free() the result.
Most of the systems have it included due to namespace pollution, but
relying on this is a bad idea. Explicit include is required for at least
Debian GNU/Hurd.
The problem was introduced in 0.7.44 (r2589) during conversion to complex
values. Previously string.len included space for terminating NUL, but
with complex values it doesn't.
The bug in question is likely already fixed (though unfortunately we have
no information available as Apple's bugtracker isn't open), and the
workaround seems to be too pessimistic for modern versions of Safari
as well as other webkit-based browsers pretending to be Safari.
- Removed "hash" element from ngx_http_header_val_t which was always 1.
- Replaced NGX_HTTP_EXPIRES_* with ngx_http_expires_t enum type.
- Added prototype for ngx_http_add_header()
- Simplified ngx_http_set_last_modified().
This resulted in a disclosure of previously freed memory if upstream
server returned specially crafted response, potentially exposing
sensitive information.

Embedded perl module assumes there is a space for terminating NUL character,
make sure to provide it in all situations by allocating one extra byte for
value buffer. Default ssi_value_length is reduced accordingly to
preserve 256 byte allocations.
While here, fixed another one byte value buffer overrun possible in
ssi_quoted_symbol_state.

It wasn't enforced for a long time, and there are reports that people
use up to 100 simultaneous subrequests now. As this is a safety limit
to prevent loops, it's raised accordingly.
ZFS reports incorrect st_blocks until file settles on disk, and this
may take a while (i.e. just after creation of a file the st_blocks value
is incorrect). As a workaround we now use st_blocks only if
st_blocks * 512 > st_size, this should fix ZFS problems while still
preserving accuracy for other filesystems.
The problem had appeared in r3900 (1.0.1).
Previous code incorrectly assumed that nodes with identical keys are linked
together. This might not be true after tree rebalance.

The cycle->new_log.file may not be set before config parsing finished if
there are no error_log directive defined at global level. Fix is to
copy it after config parsing.
