Autotools: Refactor builtin checks (#14835)

This creates a single M4 macro PHP_CHECK_BUILTIN and removes other
PHP_CHECK_BUILTIN_* macros. Checks are wrapped in AC_CACHE_CHECK and
PHP_HAVE_BUILTIN_* CPP macro definitions are defined to 1 if builtin
is found and undefined if not.

This also changes all PHP_HAVE_BUILTIN_ symbols to be either undefined
or defined (to value 1) and syncs all #if/ifdef/defined usages of them
in the php-src code. This way it is simpler to use them because they
don't need to be defined to value 0 on Windows, for example. This is
done as previous usages in php-src were mixed and on many places they
were only checked with ifdef.

refactor: change `zend_is_true` to return `bool` (#14301)

Previously this returned `int`. Many functions actually take advantage

refactor: change `zend_is_true` to return `bool` (#14301)

Previously this returned `int`. Many functions actually take advantage
of the fact this returns exactly 0 or 1. For instance,
`main/streams/xp_socket.c` does:

sockopts |= STREAM_SOCKOP_IPV6_V6ONLY_ENABLED * zend_is_true(tmpzval);

And `Zend/zend_compile.c` does:

child = &ast->child[2 - zend_is_true(zend_ast_get_zval(ast->child[0]))];

I changed a few places trivially from `int` to `bool`, but there are
still many places such as the object handlers which return `int` that
should eventually be `bool`.

zend_compiler, ...: use `uint8_t` instead of `zend_uchar` (#10621)

`zend_uchar` suggests that the value is an ASCII character, but here,
it's about very small integers. This is misleading, so let's use a
C99 integer instead.

On all architectures currently supported by PHP, `zend_uchar` and
`uint8_t` are identical. This change is only about code readability.

Deprecate zend_atol() / add zend_ini_parse_quantity() (#7951)

Add zend_ini_parse_quantity() and deprecate zend_atol(), zend_atoi()

zend_atol() and zend_atoi() don't just do number parsing.
They also check for a 'K', 'M', or 'G' at the end of the string,
and multiply the parsed value out accordingly.

Unfortunately, they ignore any other non-numerics between the
numeric component and the last character in the string.
This means that numbers such as the following are both valid
and non-intuitive in their final output.

* "123KMG" is interpreted as "123G" -> 132070244352
* "123G " is interpreted as "123 " -> 123
* "123GB" is interpreted as "123B" -> 123
* "123 I like tacos." is also interpreted as "123." -> 123

Currently, in php-src these functions are used only for parsing ini values.

In this change we deprecate zend_atol(), zend_atoi(), and introduce a new
function with the same behavior, but with the ability to report invalid inputs
to the caller. The function's name also makes the behavior less unexpected:
zend_ini_parse_quantity().

`error: comparison of integer expressions of different signedness: ‘size_t’ {aka
‘long unsigned int’} and ‘long int’ [-Werror=sign-compare]`

This is asserting `end >= haystack` as a precondition for callers (in debug
builds) and existing callers are correct.

An alternate option is to cast the left side to `int64_t`, but that may be
slightly inefficient for 32-bit builds.

Optimize stripos/stristr

Closes GH-7847
Closes GH-7852

Previously stripos/stristr would lowercase both the haystack and the
needle to reuse strpos. The approach in this PR is similar to strpos.
memchr is highly optimized so we're using it to search for the first
character of the needle in the haystack. If we find it we compare the
remaining characters of the needle manually.

The new implementation seems to perform about half as well as strpos (as
two memchr calls are necessary to find the next candidate).
