Since bug@20166, which replaced the binlog file name generating to base
on pidfile_name instead of the previous glob_hostname, the binlog file
name suddenly started to be stored solely in the absolute path format,
including a case when --log-bin option meant a relative path.
What's more serious, the path for binlog file can lead unrequestedly
to pid-file directory so that after any proper fix for this bug
there might be similar to the bug report consequences for one who
upgrades from post-fix-bug@20166-pre-fix-bug@28597 to post-fix-bug@28597.
Fixed with preserving`pidfile_name' (intr.by bug@20166) but stripping
off its directory part. This restores the original logics of storing
the names in compatible with --log-bin option format and with the
requirement for --log-bin ralative path to corresond to the data directory.
Side effects for this fix:
effective fixing bug@27070, refining its test;
ensuring no overrun for buff can happen anymore (Bug#31836
insufficient space reserved for the suffix of relay log file name);
bug#31837 --remove_file $MYSQLTEST_VARDIR/tmp/bug14157.sql missed
in rpl_temporary.test;
fixes Bug@28603 Invalid log-bin default location;
mysql-test/t/rpl_dual_pos_advance.test:
After correcting the logics of log file name composing workaround for
Bug #27070 server logs are created unrequested and in wrong directory
is removed.
mysql-test/t/rpl_temporary.test:
remaining temp file of the test removed
sql/log.cc:
stripping off the directory part of `pidfile_name' for binlog name
generating (which fixes two more bugs on wrong binlog file location);
ensuring no overrun for buff can happen anymore (Bug #31836
insufficient space reserved for the suffix of relay log file name);
