By default MyISAM overwrites .MYD and .MYI files no
DATA DIRECTORY option is used. This can lead to two tables
using the same .MYD and .MYI files (that can't be dropped).
To prevent CREATE TABLE from overwriting a file a new option
is introduced : keep_files_on_create
When this is on the CREATE TABLE throws an error if either
the .MYD or .MYI exists for a MyISAM table.
The option is off by default (resulting in compatible behavior).

The Ctrl-C handler in mysql closes the console while ReadConsole()
waits for console input.
But the main thread was detecting that ReadConsole() haven't read
anything and was processing as if there're data in the buffer.
Fixed to handle correctly this error condition.
No test case added as the test relies on Ctrl-C sent to the client
from its console.

with the space character.
When the my_strnncollsp_simple function compares two strings and one is a prefix
of another then this function compares characters in the rest of longer key
with the space character to find whether the longer key is greater or less.
But the sort order of the collation isn't used in this comparison. This may
lead to a wrong comparison result, wrongly created index or wrong order of the
result set of a query with the ORDER BY clause.
Now the my_strnncollsp_simple function uses collation sort order to compare
the characters in the rest of longer key with the space character.

An assertion abort could occur for some grouping queries that employed
decimal user variables with assignments to them.
The problem appeared the constructors of the class Field_new_decimal

Fixed bug #29417.
An assertion abort could occur for some grouping queries that employed
decimal user variables with assignments to them.
The problem appeared the constructors of the class Field_new_decimal
because the function my_decimal_length_to_precision did not guarantee
returning decimal precision not greater than DECIMAL_MAX_PRECISION.
Now if the precision returned by calls to my_decimal_length_to_precision
in the constructors of the class Field_new_decimal is greater than
DECIMAL_MAX_PRECISION the precision is set to this value.
The cast operation ignored the cases when the precision and/or the scale exceeded
the limits, 65 and 30 respectively. No errors were reported in these cases.
For some queries this may lead to an assertion abort.
Fixed by throwing errors for such cases.

For GCov builds, if the server crashes, the normal exit handler for writing
coverage information is not executed due to the abnormal termination.
Fix this by explicitly calling the __gcov_flush function in our crash handler.
The need arose when working on Bug 26141, where it became
necessary to replace TABLE_LIST with its forward declaration in a few
headers, and this involved a lot of s/TABLE_LIST/st_table_list/.
Although other workarounds exist, this patch is in line
with our general strategy of moving away from typedef-ed names.
Sometime in future we might also rename TABLE_LIST to follow the
coding style, but this is a huge change.
