da8fc25a98 Start to overhaul RAND API
Remove unused rand_hw_xor, MD/EVP indirection
Make rand_pseudo same as rand.
Cleanup formatting and ifdef control
Rename some things:
    - rand_meth to openssl_rand_meth; make it global
    - source file
    - lock/init functions, start per-thread state
    - ossl_meth_init to ossl_rand_init
Put state into RAND_STATE structure
And put OSSL_RAND_STATE into ossl_typ.h
Use "randomness" instead of "entropy"

These are the remaining easy ones to cover a recently removed commit.
Some are trivial, some have been modified and a couple left as they are because the reverted change didn't bounds check properly.

9ee344f5cd Cleanup RAND_load_file,RAND_write_file
Document an internal assumption that these are only for use with files,
and return an error if not. That made the code much simpler.
Leave it as writing 1024 bytes, even though we don't need more than 256
from a security perspective.  But the amount isn't specified, now, so we
can change it later if we want.

5006b37b31 In rand_cleanup_int(), don't go creating a default method
If no default method was yet given, RAND_get_rand_method() will set it
up.  Doing so just to clean it away seems pretty silly, so instead,
use the default_RAND_meth variable directly.

This also clears a possible race condition where this will try to init
things, such as ERR or ENGINE when in the middle of a OPENSSL_cleanup.

Fixes #3128

This removes the fips configure option. This option is broken as the

FIPS_mode() and FIPS_mode_set() are retained for compatibility, but
FIPS_mode() always returns 0, and FIPS_mode_set() can only be used to
turn FIPS mode off.

135648bcd0 Fix mem leaks during auto-deinit
Certain functions are automatically called during auto-deinit in order
to deallocate resources. However, if we have never entered a function which
marks lib crypto as inited then they never get called. This can happen if
the user only ever makes use of a small sub-set of functions that don't hit
the auto-init code.

This commit ensures all such resources deallocated by these functions also
init libcrypto when they are initially allocated.

Now we try %RANDFILE% first, and then the same set of environment vars
as GetTempFile() uses, i.e. %TMP%, then %TEMP%, %USERPROFILE% and
%SYSTEMROOT%. If all else fails we fall back to %HOME% and only then "C:".

fa64e63373 Use BCryptGenRandom on Windows 7 or higher
When openssl is compiled with MSVC and _WIN32_WINNT>=0x0601 (Windows 7), BCryptGenRandom is used instead of the legacy CryptoAPI.

This change brings the following benefits:
- Removes dependency on CryptoAPI (legacy API) respectively advapi32.dll
- CryptoAPI Cryptographic Service Providers (rsa full) are not dynamically loaded.
- Allows Universal Windows Platform (UWP) apps to use openssl (CryptGenRandom is not available for Windows store apps)
