Fix egrep syntax error in .deb preinst.

remove building pbxt by default in any configuration (need explicit ./configure --with-pbxt-storage-engine )

huge space usage), and there is no upstream support anymore.

file_contents.test. Also fix some old references to 5.3 in .deb packaging
found while debugging this.

The line in the file_contents.test removes all the '/lib' substrings from the
path, so file cannot be found if a path contains such a substring.
As i didn't find where it is needed, the line was just removed

per-file comments:
  mysql-test/t/file_contents.test
mdev57 5.5 main.file_contents fails on debian5-i386-fulltest.
        no '/lib' substring cutting.

In 5.5, ssl_do() no longer calls report_errors() in case of ssl error.
Since report_errors() iterated over the list of errors, this means that we
now report the first error in the list, rather than the last. Adjust the
--replace_regex line for OpenSSL build accordingly in the test case.

I want to avoid that upgrades silently change important config parameters
that users have come to rely on. This could happen if users changed their
my.cnf themselves, and then an upgrade introduces mariadb.cnf which silently
overrides the settings in my.cnf. Avoid this by having mariadb.cnf mostly
empty for now, and in the future we can add just new mariadb-specific
options there that do not break existing installations.

It needs recompilation for embedded server, as layout of THD is different in embedded.

mysql-common and places mariadb-specific stuff in /etc/mysql/conf.d/mariadb.cnf.
This should allow to co-exist with default Debian mysql-common package and
help resolve dependencies when installing mariadb among multiple available
versions of MySQL from different repositories.

This gives the wrong path when testing installed server, and we
set the correct path in my.cnf anyway.

Always define UT_DBG_ABORT in innodb/xtradb, also on Windows. This will avoid endless hangs inside ut_dgb_stop_thread

Preprocessor macros USE_MYSYS_NEW and -DSAFEMALLOC are 
used to conditionally compile safemalloc or overwritten new/delete.

-Define dummy symbol in my_new.cc in case -DUSE_MYSYS_NEW is not set.
This avoids compiler/linker warnings about an essentially empty file
being compiled.

nes prefixed with .\ or ./
- Add my_basename() to mysys.
- Do not compile files that are not needed on Windows (my_addr_resolve, an
d safemalloc related stuff it it is not used)
Avoids linker warnings about compilation of essentially empty files.

The root cause is that after recent fixes around --debug variable (lp:909051)
the variable is now available in both release and debug builds, such that MTR
cannot tell a debug compiled server from optimized one.

To fix, assign a special default value 'disabled' for 'debug' variable in optimized build
and fix MTR to check for this special value to recognize optimized build.
