Changed the creation of the .MRG file so that only the table  name
is written when the MyISAM table is in the same database as the
MERGE table, a relative path is used in other cases in mysqld,
and possibly an absolute path is used in an embedded server.
No test case is added as the external behaviour is unchanged.
Only the file names within the .MRG file are changed.

Merge from 4.0.

This is the second of three changesets. It contains the pure bug fix.
It also contains the second after-review fixes.
The problem was that with gcc on x86, shifts are done modulo word size. 
'value' is 32 bits wide and shifting it by 32 bits is a no-op.
This was triggered by an evil distribution of character incidences. 
A distribution of 2917027827 characters made of 202 distinct values led to
34 occurrences of 32-bit Huffman codes.
This might have been the first time ever that write_bits() had to write
32-bit values. Since it can be expected that one day even 32 bits might
be insufficient, the third changeset suggests to enlarge some variables
to 64 bits.

  Fix a problem in crash recovery of .ibd files on Windows if the user used lower_case_table_names=0 or 2; the directory scan in crash recovery forgot to put all paths to lower case, so that the tablespace name would be consistent with the internal data dictionary of InnoDB; remember that InnoDB puts internally all database names and table names to lower case on Windows, regardless of the value of lower_case_table_names

person who fixes the hang will correct the merged blackhole.result or ask me to).

 - Implemented ha_archive::rename_table
 - Added testcases for rename

  - Print readline or libedit version

  post review fix.
  don't init hash value on restart operations
  make sure that lock mode is correct in entire que.
