If the BIO unexpectedly fails to flush then SMIME_crlf_copy() was not
correctly reporting the error. We modify it to properly propagate the
error condition.

When creating a signed S/MIME message using SMIME_write_CMS()
if the reading from the bio fails, the state is therefore
still ASN1_STATE_START when BIO_flush() is called by i2d_ASN1_bio_stream().
This results in calling asn1_bio_flush_ex cleanup but will only
reset retry flags as the state is not ASN1_STATE_POST_COPY.
Therefore 48 bytes (Linux x86_64) leaked since the
ndef_prefix_free / ndef_suffix_free callbacks are not executed
and the ndef_aux structure is not freed.
By always calling free function callback in asn1_bio_free() the
memory leak is fixed.

which has been deprecated and replaced by the "Apache License 2.0".

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.
Merge (now really small) mem_dbg.c into mem.c

The BIO_FLAGS_NONCLEAR_RST flag behavior was not properly documented
and it also caused the length to be incorrectly set after the reset
operation.

If you use a BIO and set up your own buffer that is not freed, the
memory bio will leak the BIO_BUF_MEM object it allocates.
The trouble is that the BIO_BUF_MEM is allocated and kept around,
but it is not freed if BIO_NOCLOSE is set.
The freeing of BIO_BUF_MEM was fairly confusing, simplify things
so mem_buf_free only frees the memory buffer and free the BIO_BUF_MEM
in mem_free(), where it should be done.
Alse add a test for a leak in the memory bio
Setting a memory buffer caused a leak.
