- fix xtradb compile failures on windows (why do we have to do it again?)

conflict every time they make a change)

InnoDB does not bother to free explicitly one-time allocations at exit, so we get lots of
"still reachable" warnings in Valgrind with innodb-use-sys-malloc enabled.

Due to a bugfix for enum options in MariaDB, my_getopt parses enums into an ulong.
However, some new code from MySQL was written to assume enums take an uint.

Fix by using the correct type.

(The new MySQL code in addition had an implicit assumption that my_bool and uint were
compatible; remove this assumption).

  Fix wrong merge of result file conflicts.

from the default build. We have xtradb instead.

- Don't follow mainline on use of UNINIT_VAR yet, we haven't merged it in.

- Post-merge fixes

* Finished Monty and Jani's merge
* Some InnoDB tests still fail (because it's old xtradb code run against
  newer testsuite). They are expected to go after mergning with the latest
  xtradb.

 - Add conditionals for bundled zlib and innodb plugin.
 - Apply patch from bug#46834 to install the test suite in RPMs.
 - Add plugins to RPMs.  Disable example plugins.

This is a partial correction to the original fix for bug#37098
   Get rid of "Installed (but unpackaged)" files in the RPM build
which used a wrong variable.

man/Makefile.am:
  Correction to the original fix:
  The variable to use is "$(mandir)", "$(manlibdir)" was wrong.

This involves merge changesets and backports into QSP builds only,
does not cause a contents change in 5.1

not ready to run with innoplug-1.0.4.

automerge didn't handle this correctly,
so test "view" was corrected manually.

The test for the 45806 entry in our bug DB got applied twice,
in different places for the "view.test" and "view.result" files.

The fix is to simply remove the erroneous insertion.
