Since `bcpowmod()` does not support non-integral operands, we have to
truncate these in addition to emitting a respective warning. We also
have to work with the truncated values in the following.
We recognize that the division by one to enforce the truncation is
actually overkill, but we stick with it for now, and shall tackle the
issue for PHP 7.3.
We back-port https://github.com/libgd/libgd/commit/dd48286 even though
we cannot come up with a regression test, because the erroneous
condition appears to be impossible to trigger.
We also parenthesize the inner ternary operation to avoid confusion.
We have to make sure to avoid alpha-blending issues by explicitly
switching to `gdEffectReplace` and to restore the old value afterwards.
This is a port of <https://github.com/libgd/libgd/commit/a7a7ece>.
PHP contained two different off-by-one errors, which are fixed here. First,
it created a buffer of size HOST_NAME_MAX, not adding space for a null
terminator. Second, it subtracted 1 from the size of that buffer when passing
its size to gethostname(), despite gethostname() expecting it to be a buffer
size including space for a terminating null byte, not a string length.
The WDDX specification[1] requires to serialize floats with a decimal
point, but `snprintf()` is locale-dependent and may use a decimal
comma. We fix that afterwards by replacing an eventual comma with a
point.

Directly fail unserialization when trying to acquire an r/R
reference to an UNDEF HT slot. Previously this left an UNDEF and
later deleted the index/key from the HT.
What actually caused the issue here is a combination of two
factors: First, the key deletion was performed using the hash API,
rather than the symtable API, such that the element was not actually
removed if it used an integral string key. Second, a subsequent
deletion operation, while collecting trailing UNDEF ranges, would
mark the element as available for reuse (leaving a corrupted HT
state with nNumOfElemnts > nNumUsed).
Fix this by failing early and dropping the deletion code.

This commit makes the cURL config script aware of debian/ubuntu
[multiarch support][1] which installs architecture specific
headers in a different location.
It checks whether the `dpkg-architecture` script exists and is
executeable, if that is the case, the multiarch architecture is
detected by calling `dpkg-architecture -qDEB_HOST_MULTIARCH` as
documented in [debian multiarch implementation docs][2]:

The HTML decoding filter uses the `opaque` member of mbfl_convert_filter
as buffer, but there was no copy constructor defined, what caused double
frees when the filter is copied (what happens multiple times in mb_strcut(),
for instance).
This patch fixes configure error on some systems such as Alpine.

Thank you for considering merging this.
The original bug report had it returning '\0',
but with a fix to abstract name handling (6d2d0bbda7)
it now actually returns ''.
Neither of these are good, as per unix(7)
an empty socket name indicates an unbound name
and "should not be inspected".
