Mostly, this affected files (programs, scripts, and manual pages)
which got built during a RPM build but were not listed in the
appropriate "%files" section of the "spec" file.
This is fixed now, they are added.

To make this consistent, this patch also makes the build of "innochecksum"
(and its inclusion in a tar.gz or other package) depend on whether InnoDB
is configured in the build.

Also, some tools to create Windows packages are irrelevant in any binary
Unix package (not the sources !), and so they are deleted before packaging.

configure.in:
  To prevent "innochecksum" from getting built even if InnoDB is not configured
  (and then being included in such packages),
  we need an "automake condition" that evaluates whether we have InnoDB.
extra/Makefile.am:
  Evaluate the new automake condition about having InnoDB,
  and make the build of "innochecksum" depend on it.
man/Makefile.am:
  Cleanup: There are manual files which we do not need,
  like those about tools for Windows builds / packaging
  (irrelevant in any Unix binary package)
  and about NDB tools which do not get built.
scripts/make_binary_distribution.sh:
  In any Unix binary package, do not include tools for Windows builds
  (and their manual pages).
  This does not affect source packages, of course.
support-files/mysql.spec.sh:
  There were several files (binaries, scripts, and manuals)
  which got built with a RPM but never packages,
  add them to the respective RPM.

min() and max() functions are implemented in MySQL as macros.
This means that max(a,b) is expanded to: ((a) > (b) ? (a) : (b))
Note how 'a' is quoted two times.
Now imagine 'a' is a recursive function call that's several 10s of levels deep.
And the recursive function does max() with a function arg as well to dive into
recursion.
This means that simple function call can take most of the clock time.
Identified and fixed several such calls to max()/min() : including the IF() 
sql function implementation.

Range scan in descending order for c <= <col> <= c type of
ranges was ignoring the DESC flag.
However some engines like InnoDB have the primary key parts 
as a suffix for every secondary key.
When such primary key suffix is used for ordering ignoring 
the DESC is not valid.
But we generally would like to do this because it's faster.
            
Fixed by performing only reverse scan if the primary key is used.
Removed some dead code in the process.

The crash was caused by freeing the internal parser stack during the parser
execution.
This occured only for complex stored procedures, after reallocating the parser
stack using my_yyoverflow(), with the following C call stack:
- MYSQLparse()
- any rule calling sp_head::restore_lex()
- lex_end()
- x_free(lex->yacc_yyss), xfree(lex->yacc_yyvs)

The root cause is the implementation of stored procedures, which breaks the
assumption from 4.1 that there is only one LEX structure per parser call.

The solution is to separate the LEX structure into:
- attributes that represent a statement (the current LEX structure),
- attributes that relate to the syntax parser itself (Yacc_state),
so that parsing multiple statements in stored programs can create multiple
LEX structures while not changing the unique Yacc_state.

Now, Yacc_state and the existing Lex_input_stream are aggregated into
Parser_state, a structure that represent the complete state of the (Lexical +
Syntax) parser.

offset for time part in UUIDs was 1/1000 of what it
should be. In other words, offset was off.

Also handle the case where we count into the future
when several UUIDs are generated in one "tick", and
then the next call is late enough for us to unwind
some but not all of those borrowed ticks.

Lastly, handle the case where we keep borrowing and
borrowing until the tick-counter overflows by also
changing into a new "numberspace" by creating a new
random suffix.

  Show that time-part of UUIDs is correct now
  by replicating the C-code's resultin SQL.
  Results also decode to expect date-data on

  No test for unwinding of borrowed ticks as
  this a) is a race and b) depends on what timer
  we get.
sql/item_strfunc.cc:
  correct offset for date/time-part of UUID.
  also make sure that when we counted into
  the future earlier (several UUIDs generated
  in same tick), we only give back as many
  "borrowed" ticks as we can without duplicating
  past timestamps. If our tick-counter overflows
  before we can give back, or if the system-clock
  is set back (by user or Daylight Saving Time),
  we create a new random suffix to avoid
  collisions and clear the tick-counter.
