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).
