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.

Make HashContexts serializable.

Make HashContexts serializable.

* Modify php_hash_ops to contain the algorithm name and
serialize and unserialize methods.

* Implement __serialize and __unserialize magic methods on
HashContext.

Note that serialized HashContexts are not necessarily portable
between PHP versions or from architecture to architecture.
(Most are, though Keccak and slow SHA3s are not.)

An exception is thrown when an unsupported serialization is
attempted.

Because of security concerns, HASH_HMAC contexts are not
currently serializable; attempting to serialize one throws
an exception.

Serialization exposes the state of HashContext memory, so ensure
that memory is zeroed before use by allocating it with a new
php_hash_alloc_context function. Performance impact is
negligible.

Some hash internal states have logical pointers into a buffer,
or sponge, that absorbs input provided in bytes rather than
chunks. The unserialize functions for these hash functions
must validate that the logical pointers are all within bounds,
lest future hash operations cause out-of-bounds memory accesses.

* Adler32, CRC32, FNV, joaat: simple state, no buffer positions
* Gost, MD2, SHA3, Snefru, Tiger, Whirlpool: buffer positions
must be validated
* MD4, MD5, SHA1, SHA2, haval, ripemd: buffer positions encoded
bitwise, forced to within bounds on use; no need to validate

SHA-3 Keccak_Hash: Store Keccak_HashInstance in the main context.

This could cause memory leaks on errors. For instance,

SHA-3 Keccak_Hash: Store Keccak_HashInstance in the main context.

Previously, the Keccak_HashInstance was separately allocated.
This could cause memory leaks on errors. For instance,
in php_hash_do_hash_hmac, the following code cleans up after
a file read error:

if (n < 0) {
efree(context);
efree(K);
zend_string_release(digest);
RETURN_FALSE;
}

This does not call the context's hash_final operation, which
was the only way to free the separately-allocated Keccak state.

The simplest fix is simply to place the Keccak_HashInstance state
inside the context object. Then it doesn't need to be freed.

As a result, there is no need to call hash_final in the
HashContext destructor: HashContexts cannot contain internally
allocated resources.

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.
