f7b573b4e9 Support fixed address mmap without replacement
Reapply changes for Zend fixed mapping but only for FreeBSD.
Other BSD might expose some day a similar flag (private
for OpenBSD for the moment for example).
The Linux's part could be brought back but not before 7.4,
at this time, distributions with kernel > 4.17 will be
more widely available.

446b5b15d3 Don't report mmap failure if it is expected
When using mmap with MAP_FIXED_NOREPLACE or MAP_FIXED|MAP_EXCL
an mmap failure is not an error condition, so do not print an
error message in this case.

0f68ff5c92 Support fixed address mmap without replacement
We did not use MAP_FIXED here, because it may replace an existing
mapping. This commit adds support for MAP_FIXED_NOREPLACE (available
on newer Linux kernels) and MAP_FIXED|MAP_EXCL (available on FreeBSD),
which avoid this issue.

8d3f8ca12a Remove unused Git attributes ident
The $Id$ keywords were used in Subversion where they can be substituted
with filename, last revision number change, last changed date, and last
user who changed it.

In Git this functionality is different and can be done with Git attribute
ident. These need to be defined manually for each file in the
.gitattributes file and are afterwards replaced with 40-character
hexadecimal blob object name which is based only on the particular file
contents.

This patch simplifies handling of $Id$ keywords by removing them since
they are not used anymore.

5880428dac Fix potential memory issue with USE_ZEND_ALLOC=0
The PHP core and extensions are written with the assumption that memory
allocation either succeeds, or the allocator bails out (i.e. the allocator
is infallible). Therefore the result of emalloc() and friends are not checked
for NULL values.

However, with USE_ZEND_ALLOC=0, malloc() and friends are used as allocators,
but these are fallible, i.e. they return NULL instead of bailing out if they
fail. This easily leads to invalid memory accesses in the following, such as
in <https://bugs.php.net/73032>. Some of these cases may constitute
exploitable vulnerabilities.

Therefore we make the infallible __zend_alloc() and friends the default for
USE_ZEND_ALLOC=0.
