/*
About checksum calculation.
There are two types of checksums. Table checksum and row checksum.
Row checksum is an additional byte at the end of dynamic length
records. It must be calculated if the table is configured for them.
Otherwise they must not be used. The variable
MYISAM_SHARE::calc_checksum determines if row checksums are used.
MI_INFO::checksum is used as temporary storage during row handling.
For parallel repair we must assure that only one thread can use this
variable. There is no problem on the write side as this is done by one
thread only. But when checking a record after read this could go
wrong. But since all threads read through a common read buffer, it is
sufficient if only one thread checks it.
Table checksum is an eight byte value in the header of the index file.
It can be calculated even if row checksums are not used. The variable
MI_CHECK::glob_crc is calculated over all records.
MI_SORT_PARAM::calc_checksum determines if this should be done. This
variable is not part of MI_CHECK because it must be set per thread for
parallel repair. The global glob_crc must be changed by one thread
only. And it is sufficient to calculate the checksum once only.

TODO: make a number of threads a parameter TODO: make a number of threads a parameter
In parallel repair we use one thread per index. There are two modes:
Quick
Only the indexes are rebuilt. All threads share a read buffer.
Every thread that needs fresh data in the buffer enters the shared
cache lock. The last thread joining the lock reads the buffer from
the data file and wakes all other threads.
Non-quick
The data file is rebuilt and all indexes are rebuilt to point to
the new record positions. One thread is the master thread. It
reads from the old data file and writes to the new data file. It
also creates one of the indexes. The other threads read from a
buffer which is filled by the master. If they need fresh data,
they enter the shared cache lock. If the masters write buffer is
full, it flushes it to the new data file and enters the shared
cache lock too. When all threads joined in the lock, the master
copies its write buffer to the read buffer for the other threads
and wakes them.

NOTE
Dynamic Records With Non-Quick Parallel Repair
For non-quick parallel repair we use a synchronized read/write
cache. This means that one thread is the master who fixes the data
file by reading each record from the old data file and writing it
to the new data file. By doing this the records in the new data
file are written contiguously. Whenever the write buffer is full,
it is copied to the read buffer. The slaves read from the read
buffer, which is not associated with a file. Thus read_cache.file
is -1. When using _mi_read_cache(), the slaves must always set
flag to READING_NEXT so that the function never tries to read from
file. This is safe because the records are contiguous. There is no
need to read outside the cache. This condition is evaluated in the
variable 'parallel_flag' for quick reference. read_cache.file must
be >= 0 in every other case.
RETURN
-1 end of file
0 ok
> 0 error
