This replaces uses of:
memcpy(dst, src, strlen(src))
with:
strcpy(dst, src)
This fixes issues with reading past the end of the copied buffer
(e.g. when processing word-based replacements for emoji characters)
by ensuring that the destination buffer is null terminated.

Clang static analysis reports an 'Assigned value is garbage or
undefined' for this. If no points were read from the file, the
`n_points` variable is 0 and `env_x[n_points-1]` performs an
out-of-bounds access.
Clang static analysis reports an 'Assigned value is garbage or
undefined' error. This happens if the default_tune data has not
been copied in the kTUNE case.
Extending this further, it does not make sense to save the tune
data if the tune was not found, or if the tune already exists.
This was identified by the clang static analyser. The letter
variable is set in the various match_type switch cases, so
does not need to be initialised in the start of the while loop.
Clang static analysis reports a 'Dereference of null pointer'
error when accessing wtab->flags. This is properly guarded
against when setting the wflags variable, so use that variable
instead.
Clang static analysis reports this as several 'Result of operation
is garbage or undefined' errors, when `ending` has not been set
due to no matching endings.
Outside of Linux platforms, sha1 hashing from the command-line is accomplished
by commands other than sha1sum. OSX uses shasum and FreeBSD uses sha1, so I've
added in detection for the appropriate command before falling back and failing
the test.
The definitions for towlower() and towupper() are defined in /usr/include/wctype.h on FreeBSD platforms. I just removed the define and used the ucd_ equivilent where towlower/towupper were found.

FreeBSD requires __BSD_VISIBLE to be set to expose M_PI and mkstemp() in the
system includes. This is normally set when _ANSI_SOURCE, _C99_SOURCE, or
_C11_SOURCE are undefined. I don't want to dig into what the compiler is
setting, so I'm just setting it in the configure script.
