Showstopper and regression against 5.0.24.

Previously, we ignored seek() errors (see Bug#22828) and let seek()s
against pipes fail.  Now, since we check that a seek didn't fail,
and return without reading, this bug popped up.

This restores the behavior for file-ish objects that could never be 
seek()ed.


mysys/mf_iocache.c:
  If we detect early that the file is not tell()able, then we should
  assume that it's also not seek()able and therefore we should never
  set the (poorly named) "seek_not_done" flag so that we don't immedi-
  ately try to seek() when reading later.
  
  The problem was that tell() was returning -1, so when we read later, 
  we needlessly tried to seek to position  (unsigned long) -1 . 
  
  Also, if we think we're supposed to seek to a position in a file and 
  the file is un-tell()able, then abort.

Under high load it was possible that memory mapping was started on a table
while other threads were working with the table.

I fixed the start of memory mapping so that it is done at the first table
open or when the requesting thread is using the table exclusively only.


include/my_base.h:
  Bug#25460 - High concurrency MyISAM access causes severe mysqld crash.
  Added a new MyISAM open_flag HA_OPEN_MMAP.
storage/myisam/ha_myisam.cc:
  Bug#25460 - High concurrency MyISAM access causes severe mysqld crash.
  Replaced the call to mi_extra(... HA_EXTRA_MMAP ...) by the new open_flag
  HA_OPEN_MMAP. This effects that the mapping will no longer be done on
  every open of the table but just on the initial open, when the MyISAM
  share is created.
storage/myisam/mi_dynrec.c:
  Bug#25460 - High concurrency MyISAM access causes severe mysqld crash.
  Added a comment with a concern regarding the mmap flag MAP_NORESERVE.
storage/myisam/mi_extra.c:
  Bug#25460 - High concurrency MyISAM access causes severe mysqld crash.
  Limited the start of memory mapping to situations where the requesting
  thread has the table exclusively opened.
storage/myisam/mi_open.c:
  Bug#25460 - High concurrency MyISAM access causes severe mysqld crash.
  Added memory mapping code. Used if the new open_flag HA_OPEN_MMAP is set.
