The problem is a hack in mysqltest.c::append_field that modifies
the exponential notation of floating point numbers by removing a
zero after the the symbol 'e' (eg: 00001.2e+018 is converted to
00001.2e+18) but does not take into account the zerofill affect
in the start of the string.

The solution is to check if the field was zero filled and insert
a zero at the start of the string if a zero after the exponential
notation symbol is removed.

Adding $MASTER_MYSOCK to init_win_path()
When path names are short, master.sock ends up in MYSQL_TMP_DIR, but with longer path names,
master.sock ends up in /tmp/<random_string>/ and these tests will fail due to path delimiter difference.

New changeset to start with 5.0 -- Not all of these tests are present in 5.0, but want to keep mysqltest the same

The bug is a regression introduced by the patch for bug32798.

The code in Item_func_group_concat::clear() relied on the 'distinct'
variable to check if 'unique_filter' was initialized. That, however,
is not always valid because Item_func_group_concat::setup() can do
shortcuts in some cases w/o initializing 'unique_filter'.

Fixed by checking the value of 'unique_filter' instead of 'distinct'
before dereferencing.

The problem is that since MyISAM's concurrent_insert is on by
default some concurrent SELECT statements might not see changes
made by INSERT statements in other connections, even if the
INSERT statement has returned.

The solution is to disable concurrent_insert so that INSERT
statements returns after the data is actually visible to other
statements.

  100% effectively on Windows

The mysqltest docs state that the 'replace_result' command
doesn't perform any escape processing.
However the current implementation was processing backslash 
escapes in the from/to strings.
This prevents replacing e.g. patch on windows (where backslash
is used as a path separator).
Fixed by removing the backslash escape processing from 
'replace_result'.
