  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


innobase/btr/btr0cur.c:
  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


Docs/Makefile.am:
   - moved reservedwords.texi from info_TEXINFOS to EXTRA_DIST since it is
     not a full-featured texi file and automake would complain about
     "missing @setfilename"
Docs/manual.texi:
   - replaced manual.texi with a dummy placeholder file (manual.texi is
     now maintained in a separate "mysqldoc" BK source tree) - it will be
     replaced with the correct manual.texi when building the official
     source distribution

   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


Docs/Makefile.am:
   - added reservedwords.texi (which gets included by manual.texi)
   - removed MIRRORS (mirror list is not part of the manual anymore)
Docs/reservedwords.texi:
   - Updated wording a bit after adding it to the tree
Makefile.am:
   - removed MIRRORS from EXTRA_DIST (it's not part of the manual anymore)
ltconfig:
   - Redirect standard error when checking for dpkg-architecture
     to avoid error message showing during configuration (thanks to
     John Wythe for the patch)
sql/Makefile.am:
   - replaced YFLAGS with AM_YFLAGS to make automake happy

   - bump up version number 3.23.55 -> 3.23.56

   - make sure to use "gnutar" (on Mac OS X) to pack up the binary distribution
     (Mac OS X "tar" seems to be buggy - the resulting tarballs appear to be
     corrupted, e.g. when opening them with Midnight Commander. GNU tar seems
     to extract them correctly, though)
