Fix crash when tracing is enabled. Position after buffer was used also
direct usage of MYSQLND_STRING pointer instead of the "s" property of the
structure.
Fix a crash introduced yesterday in mysqlnd, non-zts mode - missing if () for
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.
- More statistics
- 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.
- 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
