de77344de2 Promote pack/unpack format errors

errors) should throw ValueError.

fdd9018bdf Support uuencoding empty string 
Cross checking implementations from other languages, empty strings
are always allowed. PHP's output is peculiar due to it's insistence
to encode a trailing \0, but otherwise sensible and does round-trip
as expected.

aba0ee71b2 Don't return false for empty string in soundex() 
Return "0000" instead of false to have a consistent return type.
"0000" is already a possible return value if the string doesn't
contain any letters, such as with soundex(" "). We can treat the
case of soundex("") exactly the same.

similar functions in other exts, such as mysqli_fetch_all().

edf22962ef Make constant redeclaration a warning 
We missed the change to make this an Error exception in PHP 8,
but at least elevate it to a warning, to avoid a notice -> exception
jump at a later time.

54f03d31e0 Promote invalid field to ValueError in pgsql 
The same error condition is a ValueError in mysqli, be consistent.

Additionally, do not display the argument name for these errors.
As the signatures are overloaded, the argument name may not match
the meaning at all.

d1bbc39e4c pg_unescape_bytea() can only fail on OOM 
The implementation did not check for PQunescapeBytea failure
correctly, because it checked for a null pointer after estrndup,
which certainly cannot happen. Inspection of the PGunescapeBytea
implementation has shown that this function can only fail on OOM,
so let's check for that explicitly and remove false as a possible
return type.

While we're here, avoid an unnecessary copy of the result.

12306728c5 Add system ID entropy API 
The `zend_system_id` is a (true global) system ID that fingerprints a process state. When extensions add engine hooks during MINIT/startup, entropy is added the system ID for each hook. This allows extensions to identify that changes have been made to the engine since the last PHP process restart.

Closes GH-5871

34bb5ba2ea Remove support for EXT_NOP 
This is an annoying edge case that regularly gets broken. As we're
not aware of significant users of this API, and there are other
ways to hook this, remove support for EXT_NOP.
