If a binlog file is manually replaced with a namesake directory the internal purging did
not handle the error of deleting the file so that eventually
a post-execution guards fires an assert.
Fixed with reusing a snippet of code for bug@18199 to tolerate lack of the file but no other error
at an attempt to delete it.
The same applied to the index file deletion.
The cset carries pieces of manual merging.

two changes. One for the bug, other manual merge.
The bug change needs MYF(0) to pass to my_delete because not all error out of the function
are critical. The finer check is done on the caller of my_delete similarly how it was implemented
for bug@18199 fixes. Non-existance of a file is not a critical error.

Bug #18453 Warning/error message if there is a mismatch between ...
There were three problems:
1. the reported lack of warnings for the BEFORE syntax of PURGE;
2. the similar lack of warnings for the TO syntax;
3. incompatible behaviour between the two in that the latter blanked out
regardlessly of presence or lack the actual file corresponding to
an index record; the former version gave up at the first mismatch.
fixed with deploying the warning's generation and synronizing logics of
purge_logs() and purge_logs_before_date().
my_stat() is called in either of two branches of purge_logs() (responsible
for the TO syntax of PURGE) similarly to how it has behaved in the BEFORE syntax.
If there is no actual binlog file, my_stat returns NULL and my_delete is
not invoked.
A critical error is reported to the user if a file from the index
could not be retrieved info about or deleted with a system error code
different than ENOENT.
sql/log.cc:
generating warning in two functions.
refining logics to call my_stat() by purge_logs() as it happens
in purge_logs_before_date().
my_delete() is called only if my_stat() ensured existance of the file.
A critical error is reported to the user if a file from the index
could not be my_stat():ed or my_delete():d with an error different
than ENOENT.
