Introducing the `assert.h` public header with the `assert(x)` macro
and already making use of it in jerry-libc sources. These newly
introduced ISO C-conforming features replace the non-conforming
`LIBC_ASSERT` and `LIBC_NDEBUG` at no cost, and they also have the
benefit that we can expose `assert` in a public header and make it
useful to jerry-libc users.

Refactor memory and string handling routines
* Potential code size improvements:
* Most loops don't really need a new incrementing index variable
running between 0..n-1 but can just loop `while (n--)`, and the
bodies don't need array indexing but can just use the `*p++`
idiom.
* Compare routines are not required to return -1, 0, and +1, but
any negative, zero, or positive result will do.
* `strncmp` may follow the other routines and does not have to have
defined behaviour if any of its args is NULL.
* Fix:
* `strncmp` did not work correctly if the strings were equal but
`n` was greater than their length (did not stop at the
terminating zero character).
Refactor printf
* Merging code duplications, removing dead initialization.
Refactor rand and srand
* Making sure that the type of the state variables is OK
(`uint32_t` instead of `unsigned int`).
* Getting type conversions OK.
* Fixing `srand` to write all state variables and thus indeed
generate the same random sequence.

The components are build independently and then are linked with main module corresponding to target platform.
Core is supposed to be platform-independent, while libc and plugins are dependent on specific architecture / platform.
The commit disables unit tests building and running during precommit.
That is supposed to be fixed in a subsequent commit.
Also, the commit disables building and running valgrind targets during precommit.
Build is supposed to be turned on by an option that should be introduced later.
Valgrind-checked runs are supposed to be performed in asynchronous mode.
