ref #10380

Fix for the init script so that the system database gets made after
running /etc/init.d/mariadb setup instead of failing silently.

CVE-2019-2510, CVE-2019-2537

The library is provided by mariadb-connector-c so remove hte
libmariadb.pc to avoid conflict.

This adds generic -latomic check so likely covers all architectures
without 64-bit atomic built-ins (e.g. armel too).

Does not seem to be needed and hopefully it fixes a deadlock on aarch64

fixes #9407

move default config to /etc/my.cnf and /etc/my.cnf.d/. This is to make
it easier to ship default configs for clients, plugins and mysql,
without introducing conflicts.

We also add a post-upgrade script which makes sure that the
skip-networking setting does not disable networking in a pre-existing
config on upgrade.

needs perl to run dbug test

and move /usr/{lib,share}/mysql -> /usr/{lib.share}/mariadb

depend on mariadb-connector-c instead of providing own client lib

spitting out -static and -embedded-dev should reduce size of mariadb-dev
significantly.

Remove dependency on glibc by using gcc builtin function and no glibc
wrappers.

Currently there are no surrogates in musl for:

  __ppc_get_timebase()
  __ppc_set_ppr_low()
  __ppc_set_ppr_med()

however glibc __ppc_get_timebase() is just a wrapper for GCC builtin
__builtin_get_timebase() available since GCC 4.8 [1], so assuming that
aports on ppc64le will never be built using GCC < 4.8 we can just
switch directly to the GCC builtin function.

Also __ppc_set_ppr_{low,med}() are not available on musl but both
are simple glibc wrappers on a single asm instruction, hence there
is no harm in using asm directly instead. Actually, using asm
directly was the first solution adopted in MariaDB [2].
