Added a WinPR macro that can be used for WinPR and FreeRDP to
replace standard C assert.
It is more verbose and logs issues to WLog which makes it easier
for us to trace problems in the field.
This useful functions allows to browse all value pairs of a hashtable without
having to allocate some memory for keys and then retrieving each element.
It may also make sense with synchronized hashtables because before you were forced to
HashTable_GetKeys() and then HashTable_GetItemValue() which is locking again for each
element of the table.
FreeRDP fails to build with OpenSSL 3.0 because of usage of the `FIPS_mode`
and `FIPS_mode_set` functions, which were removed there. Just a note that
the FIPS mode is not supported by OpenSSL 1.1.* although the mentioned
functions are still there (see https://wiki.openssl.org/index.php/FIPS_modules).
Let's make FreeRDP build with OpenSSL 3.0 and fix the FIPS mode support.

Covscan report contains various memory leak defects which were marked
as important. I have spent some time analyzing them and although they
were marked as important, most of them are in error cases, so probably
nothing serious. Let's fix most of them anyway. The rest are false
positives, or too complicated to fix, or already fixed in master, or
simply I am unsure about them.

Although the `lodepng_zlib_compress` function expects the `*out` parameter
to be `NULL`, it uses `uvector_init_buffer` internally, which takes the
`*out` value. This confuses covscan, which consequently reports the following
defects:
```
double_free: Calling "ucvector_cleanup" frees pointer "zlibdata.data" which has already been freed.
double_free: Calling "ucvector_cleanup" frees pointer "compressed.data" which has already been freed.
double_free: Calling "ucvector_cleanup" frees pointer "compressed_data.data" which has already been freed.
```
Let's use the `uvector_init` function instead as in other cases to make
covscan happy and to make the code more bulletproof. Consequently, also
remove the outdated comments.
