There is no need to cast the result of library functions that return void *;
it makes your code hard to read, adds no value, and can hide a bug if you don't
have a valid prototype in scope.

Allows to pass -march=native to dindxer projects and to libpqtypes.
CMake min version raised to 3.3 since externalproject_add didn't
support generator expressions prior to that version.
The program now tries to be more strict about the command lines it
accepts. See the comment added into main.c for more details.
Also fixed a bug introduced by a previous commit, and another one
about argv not being null-terminated. For some reasons it never
gave problems until now. But it's fixed now, so yeah.
I'm not sure this is something that should be in the code, since
compgen -W "delete locate navigate query scan" loc
would do just the same as
dindexer --printactions=loc
so this is a duplicated functionality. However this commit is
self-contained, so it should be easy to revert it, if needed.
This ends the scantask refactoring. It is now possible to scan
directories using the new system. Progress feedback is made
available again, although it could use some improvements.
set_listing must sort by abs_path, because the path received by
lower_bound() is an absolute path.
Inside hash_dir() the path passed to append_to_vec() is really
the basename of the current item. This will become more clear
in one of the next commits.
