### Description I am creating a module that uses a 3rd party library(wolfSSL), that depending on build flags, requires alignment of memory blocks to be the same as `malloc`, i.e., 16 bytes on gcc/AMD64.
It seems that `shm_malloc` returns memory aligned to 8 bytes.
Since system malloc always returns 16-byte aligned memory, it might be good to match that behaviour in `shm_malloc` in case future kamailio modules use libraries that expect this.
### Expected behavior
`shm_malloc` returns memory aligned on `__alignof__(_max_align_t) == 16`
#### Actual observed behavior
`shm_malloc` returns blocks aligned on 8-bytes
#### Debugging Data When allocating `*SSL_CTX` and `*SSL ` structs by tls module they occassionally will have 8 byte (and not necessarily 16-byte) alignments. OpenSSL does not require 16-byte alignments but wolfSSL requires 16-byte alignments.
### Possible Solutions
* The custom memory allocators in WIP `tls_wolfssl/` could try to wrap around `shm_malloc`. * have a static build of wolfSSL that does not require 16-byte alignment
### Additional Information
The default `./configure` build of wolfSSL has structs that require 16-byte alignment. wolfSSL library has a configure flag `--enable-aligndata=no` that relaxes this requirement.
