Fix GH-12936: hash() function hangs endlessly if using sha512 on strings >= 4GiB

There's two problems:
- Some loops used `unsigned int` instead of `size_t`.
- The 2*N-bit addition that is emulated using 2 N bit numbers has a bug:
it first truncated the number to 32/64 bit and only then shifted. This
resulted in the wrong length info stored inside the resulting hash.

Closes GH-12937.

hash: Support custom algo parameters

The concrete need on this change is to support passing an initial seed
to the murmur hash. Passing a custom seed is important in terms of
randomizing the hash function.

The suggested implementation adds a HashTable parameter to all the
init callbacks. Further on, an array with custom arguments is accepted
from `hash` or `hash_init` from the user land. Currently several things
like `hash_hkdf` are not touched, as they don't need passing custom
args.

Some convenience macros have been added to the SHA/MD families of
functions, so the consuming code doesn't have to be changed widely.

Another way to implement this is to add another type of the init that
would accept a HT with arguments. However, that would still require
touching all the context structs in all the algos. That would also
increase the size of those structs. As an init function is called just
once, the way of modifying the existing init callback has been seen
as more preferrable.

Closes GH-6400.

Report errors from stream read and write operations

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.

Remove local variables

This patch removes the so called local variables defined per
file basis for certain editors to properly show tab width, and
similar settings. These are mainly used by Vim and Emacs editors
yet with recent changes the once working definitions don't work
anymore in Vim without custom plugins or additional configuration.
Neither are these settings synced across the PHP code base.

A simpler and better approach is EditorConfig and fixing code
using some code style fixing tools in the future instead.

This patch also removes the so called modelines for Vim. Modelines
allow Vim editor specifically to set some editor configuration such as
syntax highlighting, indentation style and tab width to be set in the
first line or the last 5 lines per file basis. Since the php test
files have syntax highlighting already set in most editors properly and
EditorConfig takes care of the indentation settings, this patch removes
these as well for the Vim 6.0 and newer versions.

With the removal of local variables for certain editors such as
Emacs and Vim, the footer is also probably not needed anymore when
creating extensions using ext_skel.php script.

Additionally, Vim modelines for setting php syntax and some editor
settings has been removed from some *.phpt files. All these are
mostly not relevant for phpt files neither work properly in the
middle of the file.

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.
