* version_compile_os can be "linux-systemd", not equal to "Linux"

has one_thread_per_connection is guaranteed to fail.
This patch adds for "--ps-protocol" second execution
of queries "SELECT".
Also in this patch it is added ability to disable/enable
(--disable_ps2_protocol/--enable_ps2_protocol) second
execution for "--ps-prototocol" in testcases.
Failed attempt to load dynamic library with STB_GNU_UNIQUE symbol may corrupt
internal dynamic linker data sructures. This looks like libdl bug:
https://sourceware.org/bugzilla/show_bug.cgi?id=14577
In embedded mode "show plugins soname" fails to dlopen ha_mroonga.so (which

It crashes later in subsequent call to dlopen() from pthread_exit().
Disabled plugins.show_all_plugins until dlopen() bug is fixed.
