Except for the added (and sorted) includes, and the removal of redundant
parentheses, this patch can be approximated with the following semantic
patch:
$ cat ~/tmp/spatch/streq.sp;

- strcmp(a, b) == 0

$ find contrib/ lib* src/ -type f \
| xargs spatch --sp-file ~/tmp/spatch/streq.sp --in-place;

- Integer variables convert to each other.
I changed the declaration of a few variables in order to allow removing
a cast.
However, I didn't attempt to edit casts inside comparisons, since they
are very delicate. I also kept casts in variadic functions, since they
are necessary, and in allocation functions, because I have other plans
for them.
I also changed a few casts to int that are better as ptrdiff_t.
This change has triggered some warnings about const correctness issues,
which have also been fixed in this patch (see for example src/login.c).
