Add hash_free_all() to factor common code of iterating over all
members of a hash to free them with a single nasm_free().
Split strtbl_find() into strtbl_find() and strtbl_add(). It is very
unlikely that the same call site will want to have both of these
functionalities, and in the end the code for the two functions are
surprisingly different.

Several output formats use "string tables", which is a collection of
null-terminated (C) strings which are referenced by a byte offset into
the string table. A single string can be referenced an arbitrary
number of times.
As this is quite simple to implement with a hash table, we do exactly
that.

Add a function to splice a pathname consisting of a directory and a
filename. It is worth noting that this function is limited to that
particular use case: in particular, it does NOT currently support
concatenating a filename which itself contains directory components to
a non-null directory.
Combining directory names is extremely system-dependent and probably
needs more than just parameterized code in many cases, for example,
on VMS combining "foo:[bar]" with "[baz]quux" should produce
"foo:[bar.baz]quux" whereas combining "foo:[bar]" and baz:quux" is an
outright error.

Some debugging formats may need to be able to split paths into
directory name and filename, at least. This is kind of iffy, at least
across platforms, but that isn't really expected to be an issue in
practice... we hope.

The --enable-sections option isn't too useful without

--enable-lto seems to completely break RPM debug information, so fall
back on --enable-sections, which at least allows the linker to do
better dead code removal.

Remove casts from allocations. This is simply Not How To Do Things:
every cast carries a potential risk of being a toxic type misuse
(e.g. pointer as integer) and so any unnecessary cast is actively
harmful.
Note that a lot of allocations here are completely unnecessary: the
core code now guarantees that all filenames are permanently allocated
for the duration of the assembly, and so should be turned into const
char * without any further allocation. Any remaining malloc+strcpy
should be turned into nasm_strdup(), and nasm_new[n]() used whereever
possible.
