Calling sqlite3_reset() when a result set object is freed can cause
undesired and maybe even hard to track interference with other result
sets. Furthermore, there is no need to call sqlite3_reset(), because
that is implicitly called on SQLite3Stmt::execute(), and users are
encouraged to explicitly call either SQLite3Result::finalize() or
SQLite3Stmt::reset() anyway.
We return all integers that can be represented as such by PHP as
integers, and only those that exceed the possible range as strings.
On builds which represent integers with 64 bits, the range check is
unnecessary and might cause code checkers to complain, so we skip this
special casing via the preprocessor according to
<http://git.php.net/?p=php-src.git;a=commit;h=99d087e5>.
If a userwrapper opener E_ERRORs then FG(user_stream_current_filename)
would remain set until the next request and would not be pointing
at unallocated memory.
Catch the bailout, clear the variable, then continue bailing.

The color components are supposed to be in range 0..255, so we must not
cast them to `signed char`, what can be the default for `char`.

...from FILTER_VALIDATE_BOOLEAN, FILTER_NULL_ON_FAILURE
The remainer of the fix would require the filter functions to only
convert to string when it makes sense for that particular filter.

`command_length` is retrieved via strlen() and later passed to emalloc()
and memcpy(), so the appropriate type is `size_t`.
We don't add a regression test, because that would need to allocate a string
of at least 2 GiB.
gdImageTrueColorToPalette() is sometimes wasteful by putting multiple white
color entries into the palette. This is caused by an obvious typo, where
to avoid a division by zero when `total` is zero, `count` is checked instead
of `total`.
We fix this issue to improve the quality of the color quantization.

`from` and `len` are `long`, but get passed to mbfl_substr() which expects
`int`s. Therefore we clamp the values to avoid the undefined conversion
behavior.
