  Backport from 4.0: Fix a major bug in InnoDB query estimator for queries of type SELECT ... WHERE col < x and SELECT ... WHERE col > x; MySQL could pick a table scan though the result set was only a few rows in a big table

   now maintained in a separate "mysqldoc" BK source tree) - it will be
   replaced with the correct manual.texi when building the official
   source distribution
 - fixed automake error about reservedwords.texi by moving it to EXTRA_DIST
   instead

   so it's part of the distribution (manual.texi includes this file)
   It will be replaced with the correct one from the mysqldoc tree before
   building the distribution
 - removed generation and inclusion of MIRRORS file, since the mirror list
   is no longer part of manual.texi anyway
 - replaced YFLAGS with AM_YFLAGS in sql/Makefile.am to make automake happy
 - Redirect standard error when checking for dpkg-architecture in ltconfig
   to avoid error message showing during configuration

Fixed comparision of log-binary name to handle comparison when file name extension wraps from .999 to .1000
Don't replicate CREATE/DROP DATABASE if wild_xxx_table=database.% is used.

   twice, if --enabable-thread-safe-client is enabled, which broke RPM
   building)

 - bumped up version number in configure.in to 4.0.10-gamma
