Based on the Rust clippy lint that recommends that any public
function that dereferences a raw pointer, mark all FFI functions
that reference raw pointers with build_slice and cast_pointer
as unsafe.
This commits starts by removing the unsafe wrapper inside
the build_slice and cast_pointer macros then marks all
functions that use these macros as unsafe.
Then fix all not_unsafe_ptr_arg_deref warnings from clippy.

Before, even if there were no outputs, all the arguments
were evaluated, which could turn expensive
All variables which are used only in certain build configurations
are now prefixed by underscore to avoid warnings
Unfortunately, the transition to nom 5 (and functions instead of macros)
has side-effects, one of them being requiring lots of types annotations
when using a parsing, for ex in a match instruction.
Make sure they are valid 8 bit integers before combining the
two parts into a u16 to prevent an overflow of the u16
return value.
Add unit tests to check parsing of invalid ports.
Redmine issue:
https://redmine.openinfosecfoundation.org/issues/2904
Use expectation to be able to identify connections that are
ftp data. It parses the PASV response, STOR message and the
RETR message to provide extraction of files.
Implementation in Rust of FTP messages parsing is available.
Also this patch changes some var name prefixed by ssh to ftp.
