The `encoding` attribute of the XML declaration is optional; it is good
practice to use external encoding information where available if it is
missing. Thus, we check for `charset` info of `Content-Type` headers,
and see whether the encoding is supported.
We cater to trailing parameters and quoted-strings, but not to escaped
backslashes and quotes in quoted-strings, since no known character
encoding contains these anyway.

This issue came up recently in a bug report[1]; without the error code,
users can barely guess why the function failed.

Closes GH-6745.
When opening HTTP streams, and reading the headers, we currently
discard header lines longer than `HTTP_HEADER_BLOCK_SIZE` (1024 bytes).
While this is not generally forbidden by RFC 7230, section 3.2.5, it
is not generally allowed either, since that may change the "message
framing or response semantics".
We thus fix this by allowing arbitrarily long header lines.
Closes GH-6720.
So far, `SendText()` simply separates potential email address lists at
any comma, disregarding that commas inside a quoted-string do not
delimit addresses. We fix that by introducing an own variant of
`strtok_r()` which caters to quoted-strings.
We also make `FormatEmailAddress()` aware of quoted strings.
We do not cater to email address comments, and potentially other quirks
of RFC 5322 email addresses, but catering to quoted-strings is supposed
to solve almost all practical use cases.

The lack of such a check leads to false-passes of tests on Windows
which expect no output, but produce a segfault or similar issue. I
discovered this a while ago due to bad tests in an extension I maintain.
Closes GH-6722.
When no test paths are specified this shows up when 'make test' is used on a PECL extension without specifying tests to run (or in php-src too, I guess...)
Closes GH-6717.
Don't use r0 as temporary register in math_double_long if it is
already used for a memory result.
This was already done in one branch, but not the other.
First, the `bzip2.compress` filter has the same issue as `zlib.deflate`
so we port the respective fix[1] to ext/bz2.
Second, there is still an issue, if a stream with an attached
compression filter is flushed before it is closed, without any writes
in between. In that case, the compression is never finalized. We fix
this by enforcing a `_php_stream_flush()` with the `closing` flag set
in `_php_stream_free()`, whenever a write filter is attached. This
call is superfluous for most write filters, but does not hurt, even
when it is unnecessary.
