STAT_LAST was accessing wrong memory thus overwritting method pointers.
Windows doesn't have atoll(), which is C99, C89 has only atoi() + atol().
Win has _atoi64, so use it.
- Fixed endless loop - mysqlnd_stmt_next_result() returned FAIL but as it
is defined to be 1 (and PASS is 0), checking for mysqlnd_stmt_more_result()
was successful although we were expecting a FAIL.
Clearly separated fetching (physical reading) from decoding phases (data
interpretation). Threaded fetching added but disabled as needs more work for
Windows. For Linux needs some touches to add pthreads if this is enabled,
probably with a compile-time switch.
The code reorganisation makes it easy to add also async API, similar to
cURL's one.
- Clean up a bit a type mess - 4 types less. No need to have aliases
for the same thing (unification is the name).
- New macro for Johannes mysqlnd_stmt_ro_result_metadata
----------------------------------------------------------------------
- Fix BIT problem for BIT values represented with 5 bytes. Typo.
- Make it possible with an ini variable to switch off/on statistics
collection.
- Compile-out debug checking of uneaten data from the line, when the
build is release. According to callgrind this was eating some percentage.
