Saves comitters' daily life by avoid #include-ing everything from
internal.h to make each file do so instead. This would significantly
speed up incremental builds.
We take the following inclusion order in this changeset:
1. "ruby/config.h", where _GNU_SOURCE is defined (must be the very
first thing among everything).
2. RUBY_EXTCONF_H if any.
3. Standard C headers, sorted alphabetically.
4. Other system headers, maybe guarded by #ifdef
5. Everything else, sorted alphabetically.
Exceptions are those win32-related headers, which tend not be self-
containing (headers have inclusion order dependencies).
With these macros implemented we can write codes just like we can assume
the compiler being clang. MSC_VERSION_SINCE is defined to implement
those macros, but turned out to be handy for other places. The -fdeclspec
compiler flag is necessary for clang to properly handle __has_declspec().
Integer overflow for unsigned types are fully defined in C. They
are not always problematic (but not always OK). These functions
in this changeset intentionally utilizes that behaviour.
Blacklist from UBSAN checks for better output.

An instruction is leaf if it has no rb_funcall inside. In order to
check this property, we introduce stack canary which is a random
number collected at runtime. Stack top is always filled with this
number and checked for stack smashing operations, when VM_CHECK_MODE.

Some old implementaions of arc4random_buf(3) were ARC4 based, or
unsafe when forked, or both. Resort to /dev/urandom for those
known problematic cases. Fix [Bug #15039]

* configure.ac: clock_gettime or gettimeofday must exist.
* process.c (rb_clock_gettime): prefer clock_gettime over
gettimeofday, as the latter is obsolete in SUSv4.
* random.c (fill_random_seed): ditto.

rid of blocking at the start-up time.

secure, as documented.

getrandom(2) and read(2) (from /dev/urandom) may return a random buffer
whose length is shorter than required. This change makes sure that they
get enough buffer by using a loop.

* random.c (InitVM_Random): rename Random.raw_seed to
Random.urandom. A quick search seems there are no practical use
of this method than securerandom.rb so I think it's OK to rename
but if there are users of it, this hunk is subject to revert.
* test/ruby/test_rand.rb (TestRand#test_urandom): test for it.
* lib/securerandom.rb (SecureRandom.gen_random): Prefer OS-
provided CSPRNG if available. Otherwise falls back to OpenSSL.
Current preference is:
1. CSPRNG routine that the OS has; one of
- getrandom(2),
- arc4random(3), or
- CryptGenRandom()
2. /dev/urandom device
3. OpenSSL's RAND_bytes(3)
If none of above random number generators are available, you
cannot use this module. An exception is raised that case.

glibc still does not define the SYS_getrandom alias for
__NR_getrandom in the Linux kernel. However, installing
up-to-date Linux kernel headers (linux-libc-dev >= 3.17 package
on Debian) will get the __NR_getrandom syscall number defined
properly without relying on glibc.
This allows users with a modern kernel+headers to use the getrandom
syscall without waiting on glibc support.
