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.

  BUG#5964 - 4.1 MERGE tables regression from 4.0

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.

  a binlog propagator (A->B->C replication where B has only blackhole tables,
  B receives binlog from A, applies it to blackhole tables, writes statements
  to its binlog which it sends to C; both A and C have non-blackhole tables). B is just a proxy.
