In a2bc57e0e5, mb_detect_encoding was modified to ensure it would never
return 'UUENCODE', 'QPrint', or other non-encodings as the "detected
text encoding". Before mb_detect_encoding was enhanced so that it could
detect any supported text encoding, those were never returned, and they
are not desired. Actually, we want to eventually remove them completely
from mbstring, since PHP already contains other implementations of
UUEncode, QPrint, Base64, and HTML entities.
For more clarity on why we need to suppress UUEncode, etc. from being
detected by mb_detect_encoding, the existing UUEncode implementation
in mbstring *never* treats any input as erroneous. It just accepts
everything. This means that it would *always* be treated as a valid
choice by mb_detect_encoding, and would be returned in many, many cases
where the input is obviously not UUEncoded.
It turns out that the form of mb_convert_encoding where the user passes
multiple candidate encodings (and mbstring auto-detects which one to
use) was also affected by the same issue. Apply the same fix.
`2001:10::/28` is a reserved IPv6 range. But there's a typo in GH-7476,
which caused IPv6 address like `240b:0010::1` will be filtered by the
flag `FILTER_FLAG_NO_RES_RANGE`.

Closes GH-7790.
When a new process reattaches to OPcache, tracing JIT causes segfaults,
because each new process allocates its own `zend_jit_traces` and
`zend_jit_exit_groups` in SHM, although these need to be shared between
all processes.
We solve that by only allocating these structs for the first process,
and store the pointers in `accel_shared_globals`, so we can reassign
them when a new process reattaches.
Closes GH-7776.
We must not use the TSRM accessor macros in GINIT and GSHUTDOWN, but
rather use the passed pointers directly. For simplicity, we inline
`php_oci_cleanup_global_handles()`, and also the `PHP_OCI_CALL()`
macros; the latter are unlikely to be needed here, but don't hurt.
Closes GH-7766.
`hash()` and `hash_hmac()` never return `false`; only `hash_file()` and
`hash_hmac_file()` return `false` in case the data cannot be read.
Closes GH-7760.
This test fails because san-cert.pem and san-ca.pem have expired. We
fix that by using the CertificateGenerator to generate temporary certs
during the test run. Since san-cert.pem and san-ca.pem have been
identical, we only generate one certificate.
Closes GH-7763.
The amount of allocated system memory is kept in `real_size`, including
the allocated `cached_chunks`. Thus, we need to keep the proper count
at the end of the shutdown.
Closes GH-7745.
