The php_stream_read() and php_stream_write() functions now return
an ssize_t value, with negative results indicating failure. Functions
like fread() and fwrite() will return false in that case.
As a special case, EWOULDBLOCK and EAGAIN on non-blocking streams
should not be regarded as error conditions, and be reported as
successful zero-length reads/writes instead. The handling of EINTR
remains unclear and is internally inconsistent (e.g. some code-paths
will automatically retry on EINTR, while some won't).
I'm landing this now to make sure the stream wrapper ops API changes
make it into 7.4 -- however, if the user-facing changes turn out to
be problematic we have the option of clamping negative returns to
zero in php_stream_read() and php_stream_write() to restore the
old behavior in a relatively non-intrusive manner.

And convert some object to string conversion related recoverable
fatal errors into Error exceptions.
Improve exception safety of internal code performing string
conversions.
This patch adds missing newlines, trims multiple redundant final
newlines into a single one, and trims redundant leading newlines.
According to POSIX, a line is a sequence of zero or more non-' <newline>'
characters plus a terminating '<newline>' character. [1] Files should
normally have at least one final newline character.
C89 [2] and later standards [3] mention a final newline:
"A source file that is not empty shall end in a new-line character,
which shall not be immediately preceded by a backslash character."
Although it is not mandatory for all files to have a final newline
fixed, a more consistent and homogeneous approach brings less of commit
differences issues and a better development experience in certain text
editors and IDEs.

Since Autoconf 2.50+ macro AC_STRUCT_ST_BLOCKS defines the new
HAVE_STRUCT_STAT_ST_BLOCKS symbol and has deprecated the previous
HAVE_ST_BLOCKS.
PHP 5.3 required Autoconf 2.13 (released in 1999) or newer, since PHP
5.4 the autoconf 2.59 (released in 2003) or newer was required, and
since PHP 7.2, autoconf 2.64 (released in 2008) or newer is required.
Autoconf 2.50 released in 2001 has made several macros obsolete. Instead
of the AC_STRUCT_ST_BLKSIZE and AC_STRUCT_ST_RDEV the new
AC_CHECK_MEMBERS should be used.
When checking for the presence of stat struct members st_blkzize and
st_rdev the new AC_CHECK_MEMBERS macro defines new constants
HAVE_STRUCT_STAT_ST_BLKSIZE and HAVE_STRUCT_STAT_ST_RDEV.
Old constants HAVE_ST_BLKSIZE and HAVE_ST_RDEV need to be replaced
respectively in PHP code (this patch) and in PHP extenstions if they use
them.
PHP 5.4 to 7.1 require Autoconf 2.59+ version, PHP 7.2 and above require
2.64+ version, and the PHP 7.2 phpize script requires 2.59+ version which
are all greater than above mentioned 2.50 version.
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.
Prohibit direct update of GC_REFCOUNT(), GC_SET_REFCOUNT(), GC_ADDREF() and GC_DELREF() shoukf be instead.
Added mactros to validate reference-counting (disabled for now).
These macros are going to be used to eliminate race-condintions during reference-counting on data shared between threads.
If this does not break the Unix system somehow, I'll be amazed. This should get most of it out, apologies for any errors this may cause on non-Windows ends which I cannot test atm.
If a userwrapper opener E_ERRORs then FG(user_stream_current_filename)
would remain set until the next request and would not be pointing
at unallocated memory.
Catch the bailout, clear the variable, then continue bailing.
