sapi_module, mime_type_map, zend_extensions, php_cgi_globals, and phpdbg_globals are true globals which are being shadowed

[ci skip] Clarify intention in phpdbg, removing one TODO comment (#16014)

The point of WATCH_ON_BUCKET is to watch for all 3 fields of the bucket,
so the fallthrough is intended.

Fix uninitialized value watchpoint_hit

Closes GH-15317.

Fix GH-15210: phpdbg_print_changed_zvals working on a real copy instead.

Close GH-15229

Fix GH-13681: segfault when adding watchpoint fails.

thus when removing its entry, no watch point is set and crash on
pointer access.

Use more compact representation for packed arrays.

- for packed arrays we store just an array of zvals without keys.
- the elements of packed array are accessible throuf as ht->arPacked[i]
instead of ht->arData[i]
- in addition to general ZEND_HASH_FOREACH_* macros, we introduced similar
familied for packed (ZEND_HASH_PACKED_FORECH_*) and real hashes
(ZEND_HASH_MAP_FOREACH_*)
- introduced an additional family of macros to access elements of array
(packed or real hashes) ZEND_ARRAY_ELEMET_SIZE, ZEND_ARRAY_ELEMET_EX,
ZEND_ARRAY_ELEMET, ZEND_ARRAY_NEXT_ELEMENT, ZEND_ARRAY_PREV_ELEMENT
- zend_hash_minmax() prototype was changed to compare only values

Because of smaller data set, this patch may show performance improvement
on some apps and benchmarks that use packed arrays. (~1% on PHP-Parser)

TODO:
- sapi/phpdbg needs special support for packed arrays (WATCH_ON_BUCKET).
- zend_hash_sort_ex() may require converting packed arrays to hash.

Prefer userfaultfd over mprotect+SIGSEGV signal handling on linux for phpdbg watchpoints

Mark various functions with void arguments.

This fixes a bunch of [-Wstrict-prototypes] warning,
because in C func() and func(void) have different semantics.

Use ZEND_UNREACHABLE() instead of ZEND_ASSERT(0)

Instead of marking unreachable code with `ZEND_ASSERT(0)`, we introduce
`ZEND_UNREACHABLE()`, so that MSVC which does not consider `assert(0)`
to mark unreachable code does no longer trigger C4715[1] warnings in
debug builds. This may be useful for other compilers as well.

Fix phpdbg watchpoints wrt. negative_array_index RFC

The implementation of that RFC changed the initial value of
