Fix formatting issues in README file.

EXCEPTIONS-CLIENT from all the places.

If mysqltest dies, mtr waits to see if mysqld dies too within 100ms
But in that case, it should not care about expected crash
Fix: jump past the code that checks the expect file

While here, support supplying a '-j' flag to make(1) from
the environment.

Done as suggested
Also tested from src build directory

See bug #58416.

In case of low memory sort buffer QUICK_INDEX_MERGE_SELECT creates
temporary file where is stores row ids which meet QUICK_SELECT ranges
except of clustered pk range, clustered range is processed separately.
In init_read_record we check if temporary file is used and choose
appropriate record access method. It does not take into account that
temporary file contains partial result in case of QUICK_INDEX_MERGE_SELECT
with clustered pk range.
The fix is always to use rr_quick if QUICK_INDEX_MERGE_SELECT
with clustered pk range is used.

test case to give valgrind warnings.

The problem was that when comparing two MDL key buffers using
memcmp(), 1 was added to the buffer length. However, this was
no longer needed since the buffer length already included the
'\0' terminator.

Remove some more files which are unused.

and related small fixes.

Remove some more leftovers from the initial removal:

o Update relevant mentions of configure.in throughout
the source code.

o Remove win/configure.js, which at this point just
duplicates logic already present in CMake based build
system.

o Remove support files which relied on the autotools
build system. In any case, MySQL is no longer officially
supported on SCO.

o Remove files which are no longer part of the build.
