b3ae1a7b4b expr: improvements 
- handle divide by zero.
- use eregcomp().
- use emalloc().
- use snprintf() for safety and add a buffer size argument to valstr() just
  to be sure.
- code-style fixes.

e17b9cdd0a Convert codebase to use emalloc.c utility-functions 
This also definitely increases readability and makes OOM-conditions
more consistent.

7fc5856e64 Tweak NULL-pointer checks 
Use !p and p when comparing pointers as opposed to explicit
checks against NULL.  This is generally easier to read.

ec8246bbc6 Un-boolify sbase 
It actually makes the binaries smaller, the code easier to read
(gems like "val == true", "val == false" are gone) and actually
predictable in the sense of that we actually know what we're
working with (one bitwise operator was quite adventurous and
should now be fixed).

This is also more consistent with the other suckless projects
around which don't use boolean types.

ee55fbe9e9 Just make $(HDR) a prereq for $(OBJ) 
The result is always correct but it might do redundant builds.
Not really an issue as sbase builds very fast.  The alternative is
to track the header deps manually but this is already incomplete and
unlikely to be kept up to date.

5773a8f22b Implement concat() using read(2) and write(2)
