The option is '-DENABLE_BUNDLED_ZSTD' and defaults to ON.

There are two goals of making this conditional, both related to building
Tarantool on Gentoo Linux from an ebuild:

* Avoid bundled ZStd building issue w/o pay to investivage it.
* Allow user to choose between system and bundled library.

Fix misleading "C atomics not supported" when git submodules
are missing.

Closes #2088

getopt_long() is available on all supported platforms.
Get rid of legacy gopt and use getopt_long().

Incompatible changes:

 * `tarantool --version --no-such-option` printed
    "unrecognized option '--no-such-option'", now it displays version.
    `tarantool --no-such-option --version` still prints an error message.

Needed for #1265

Add an option to enable LuaJIT's GC64 mode and enable this option
by default on OS X.

Closes #2643

Remove libbfd from dependencies and use libunwind for stack traces.

Closes #2103

Inpspired by tarantool/curl module by Vasiliy Soshnikov.
Reviewed and refactored by Roman Tsisyk.

Closes #2083

This patch removes following source files regeneration:
  1. keywordhash.h
  2. opcodes.[hc]
  3. parse.[hc]
  4. sqlite3.h
adding them to the source tree.

To re-generate them (p.p. 1-3) one must pass
-DSQL_MAINTAINER_MODE=ON option to cmake. Files will be
copied to source tree automatically iif actual difference will
be detected.

As far we don't need such platform variety - remove sqlite3.h
re-generation at all.
Remove TCL script responsible for generation and template header
as well.

Compilation of auxilary SQL tools was also moved under this option:
  1. Lemon parser
  2. mkkeywordhash
since they redundant in non-maintainer mode.

Finally it removes dependency on TCL from all Tarantool package
variants.

Remove sqliteConfig.h, we don't use it.

Set working directory to root of source tree while doing
`git modules update`.

* do not include autotools build files

sql: [#2387] [#2267] Cleanup unused SQLite fines.

sql: Checkin SQLite test coverage

sql: Remove TCL-based tests

Remove sqlite-tcl testsuite along with all TCL-relared libs.
Clean up sqlite's CMakeLists and remove redundant TCL-related
sources.

	* src/lib/sqlite/CMakeLists.txt: Remove dependency on TCL library.
	* src/lib/sqlite/src/CMakeLists.txt: Remove testfixture target.
	* src/lib/sqlite/src/test.*: Remove.
	* src/lib/sqlite/src/sqlite3.rc: Ditto.
	* src/lib/sqlite/src/tclsqlite.c: Ditto.
	* src/lib/sqlite/ext: Ditto.
	* test/sqlite-tcl: Ditto.

Add -o option in lemon (output file name)

This is necessary for out-of-source CMake builds.

Use dummy commit date and UUID in sqlite3.h

Last commit date and UUID are included in generated sqlite3.h. We don't
distribute standalone sqlite, and Tarantool itself is already
version-stamped.

sqlite: Add VERSION
Implement CMake build rules for sqlite.

Sophia was an experimental storage engine in 1.6.x.
Please use 'vinyl' engine in Tarantool 1.7 instead.

Closes #2040

We don't need these functions anymore.

* Check for missing cpuid.h header
* Fix sed magic in extra/mkexports
* Fix open_memstream implementation
* Fix CLOCK_PROCESS_CPUTIME_ID / CLOCK_THREAD_CPUTIME_ID
* Disable stupid -Wchar-subscripts warnings
* Add a workaround for "undefined __gcc_personality_v0"

Tested on NetBSD 7 and on x86_64-rumprun-netbsd.
Now you can use Tarantool on toasters.

See #1874

This patch is not perfect, but it is better than nothing.

+ Remove third_party/valgrind and third_party/pmatomic which
  also exist in src/lib/small/third_party.

* Write xlog via fd instead of fiob with FILE * interface

* Remove O_DIRECT mode, use fdatasync(2)/sync_file_range(2) with
  posix_fadvise(2) to free the page cache. Disk cache polution
  on snapshot was tested with `vmtouch` utility and fadvise()
  provides similar result to O_DIRECT.

* Remove fiob.c implementation (unused)

Make sure llvm-symbolizer is available. If not, reports will contain raw
addresses instead of line info.

Since leak suppressions aren't ready yet, we suggest setting
ASAN_OPTIONS=detect_leaks=0 environment variable when running tests.
