Introduce new internal hashtable implementation

Create a new hashtable that is more efficient than the existing LHASH_OF
implementation. the new ossl_ht api offers several new features that
improve performance opportunistically

* A more generalized hash function. Currently using fnv1a, provides a
more general hash function, but can still be overridden where needed

* Improved locking and reference counting. This hash table is
internally locked with an RCU lock, and optionally reference counts
elements, allowing for users to not have to create and manage their
own read/write locks

* Lockless operation. The hash table can be configured to operate
locklessly on the read side, improving performance, at the sacrifice
of the ability to grow the hash table or delete elements from it

* A filter function allowing for the retrieval of several elements at a
time matching a given criteria without having to hold a lock
permanently

* a doall_until iterator variant, that allows callers which need to
iterate over the entire hash table until a given condition is met (as
defined by the return value of the iterator callback). This allows
for callers attempting to do expensive cache searches for a small
number of elements to terminate the iteration early, saving cpu cycles

* Dynamic type safety. The hash table provides operations to set and
get data of a specific type without having to define a type at the
instatiation point

* Multiple data type storage. The hash table can store multiple data
types allowing for more flexible usage

* Ubsan safety. Because the API deals with concrete single types
(HT_KEY and HT_VALUE), leaving specific type casting to the call
recipient with dynamic type validation, this implementation is safe
from the ubsan undefined behavior warnings that require additional
thunking on callbacks.

Testing of this new hashtable with an equivalent hash function, I can
observe approximately a 6% performance improvement in the lhash_test

Correct the documentation for OPENSSL_MALLOC_FD

The documentation was misleading in that it suggests that this environment
variable will record information about all allocations. While this is true
it doesn't record the most useful information that you might expect such
as the requested size of the allocation! It is mainly for use in
conjunction with OPENSSL_MALLOC_FAILURES, and reports information about
what chance an allocation has of failing.

We also clarify that the mem_debug functions are actually no-ops in 3.0.

Memory allocator code cleanup

Typedefs of CRYPTO malloc, realloc and free.

MEM_CHECK "modes" are used only as a CRYPTO_mem_ctrl() parameter

The CRYPTO_mem_ctrl is defined only if OPENSSL_NO_CRYPTO_MDEBUG is
defined, thus define the MEM_CHECK modes under the same condition.

Maybe the macros can be removed at all since:
1. CRYPTO_mem_ctrl() just returns -1 and ignores the parameter
2. CRYPTO_mem_ctr() is declared as DEPRECATED by 3.0

Deprecate most of debug-memory

Fixes #8322

The leak-checking (and backtrace option, on some platforms) provided
by crypto-mdebug and crypto-mdebug-backtrace have been mostly neutered;
only the "make malloc fail" capability remains. OpenSSL recommends using
the compiler's leak-detection instead.

The OPENSSL_DEBUG_MEMORY environment variable is no longer used.
CRYPTO_mem_ctrl(), CRYPTO_set_mem_debug(), CRYPTO_mem_leaks(),
CRYPTO_mem_leaks_fp() and CRYPTO_mem_leaks_cb() return a failure code.
CRYPTO_mem_debug_{malloc,realloc,free}() have been removed. All of the
above are now deprecated.

doc/man3: reformat the function prototypes in the synopses

I tried hard to keep the lines at 80 characters or less, but in a few
cases I had to punt and just indented the subsequent lines by 4 spaces.

A few well-placed typedefs for callback functions would really help, but
these would be part of the API, so that's probably for later.

I also took the liberty of inserting empty lines in overlong blocks to
provide some visual space.
