Michael F. Schönitzer 1061bd719a Change option '-m' to '-M' for consistency of cli
`-m` was added as short option for `--no-mouse`, this is inconsistence
to the rest of the cli since otherwise the short options to disable a
feature are capital letters. Therefore this commit renames the option to
`-M`.

This commit also documents the option in the man page.

Christian Göttsche 1f5bd5c4c8 Avoid modifying optarg
It might be working, but lets rather not modify getopt's global variable
`optarg`.

Also there is no need to call `getenv("USER")`, just use `geteuid()`.

Christian Göttsche 00665e2a2b Avoid unsigned integer overflow
unsigned overflow is well defined, but creates noise when using
sanitizers. unsigned overflow can be a symptom of logic issues of
counter, so its reasonable to use.

Christian Göttsche ffc65b3827 Reorder check to avoid crash on invalid process field setting
If using a setting from a different development version with an
unsupported process field, first dereferencing Process_fields[id] yields

Christian Göttsche 84d39f95c6 autotools: enable warnings and cleanup
- enable warnings in autogen script
- drop unused m4/ directory usage
- drop AC_TYPE_SIGNAL:
  C99 guarantees the signal return type to be void
- drop AC_CHECK_FILE of procdir:
  most of the time compilation is done on a different system than htop is run
  and there is a runtime check in place
- improve linux_affinity corss compile logic:
  use fourth argument instead of pre-test

Zev Weiss 2899ed4cb0 Number CPUs from zero by default.
Numbering from one is idiosyncratic and inconsistent with basically
everything else in the world; it doesn't make much sense as default
behavior.

All naming is updated to reflect that numbering from one is a
non-default, opt-in option.  The old label of the flag saved in htoprc
("cpu_count_from_zero") is still supported for backwards compatibility
with existing configs, however.

Nathan Scott c9ecd0fa74 Revert the vim_mode setting for now, needs a rethink
There have been too many bugs reported in vim_mode, and
the proposed fixes are increasingly fragile - hence we
have decided to back it out for now.  For reference:

   https://github.com/htop-dev/htop/issues/69
   https://github.com/htop-dev/htop/pull/37
   https://github.com/htop-dev/htop/pull/106

The whitespace changes also arrived in commit 12805f61d
not sure what that was about, but backed out as well.
