Before the fix for bug 48289 has been applied, the algorithm to
construct a Q-encoded-word has been optimistic, i.e. try to encode as
many bytes that *may* fit in the remaining space, calculate the actual
length of the Q-encoded word, and if it's too long, try again with a
reduced size. However, the fix for the mentioned bug replaced this by
a pessimistic algorithm, which always terminates[1] the for loop[2]
during the first iteration (which renders the following 3 lines as dead
code), and as such easily produces unnecessarily short encoded-words.
Instead the proper fix for the bug would have been to make sure that
`out_size` is always decremented, if the space isn't sufficient for the
encoded-word.

When including files in PHP tests a good practice so far has been to use
the *.inc extension. This patch renames few *.p5c files that are
included in phpt files.
The `<time.h>` header file is part of the standard C89 headers [1] and
on current systems can be included unconditionally.
Since PHP requires at least C89 or greater, the `HAVE_TIME_H` symbol
defined by Autoconf in ext/pdo_sqlite/config.m4 [2] can be ommitted and
simplifed.
Additionally, since PHP didn't define `HAVE_TIME_H` prior in the
configure.ac the occurrence of this symbol in cli can be removed.

Newer MySQL versions are stricter about invalid values. Three issues
are fixed:
* Don't use negative values with ZEROFILL. ZEROFILL implies UNSIGNED.
* Use a legal TIMESTAMP value. TIMESTAMP does not accept a Unix timestamp.
* Specify BIGINT values as strings, to avoid overflows.
This is a cherry-pick of d2dc0a3291 from master.
There were two distinct issues here:
* $trend was compared against 'NULL' using !=, which does not work
as intended in the case where $trend==0.0.
* current_targets was declared as double(17,0), which means that
the fractional part was rounded, so that the same comparison in
SQL (rounded) and in PHP (not rounded) did not necessarily
match.
Please don't write mt_rand based tests, it takes ages to debug this
crap...
The C89 standard and later defines the `<string.h>` header as part of
the standard headers [1] and on current systems it is always present.
Code included also `<strings.h>` header as an alterinative in some
files. This kind of check was relevant on some older systems where the
`<strings.h>` file included definitions for the C89 compliant
`<string.h>`. Today such alternative check is not required anymore. The
`<strings.h>` file is part of the POSIX definition these days.
Also Autoconf suggests doing this and relying on C89 or above [2] and [3].
This patch also cleans few unused `<strings.h>` inclusions in the libmbfl.

This is an internal glibc macro, it should not be necessary to use
it if we already define _GNU_SOURCE (we do through
AC_USE_SYSTEM_EXTENSIONS). Needing to use __USE_GNU generally
indicates an inclusion order problem (libc header included before
config.h).
