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
to a crash:

Clean up some code duplication in the header files
...
PR htop-dev/htop#70 got rid of the infrastructure for generating header
files, but it left behind some code duplication.
Some of cases are things that belong in the header file and don't need
to be repeated in the C file. Other cases are things that belong in the
C file and don't need to be in the header file.
In this commit I tried to fix all of these that I could find. When given
a choice I preferred keeping things out of the header file, unless they
were being used by someone else.

`env` is allocated by checked allocation functions and can not be NULL.
This checks confuses clang analyzer and causes a null-dereference

Axe automated header generation.
...
Reasoning:
- implementation was unsound -- broke down when I added a fairly
basic macro definition expanding to a struct initializer in a *.c
file.
- made it way too easy (e.g. via otherwise totally innocuous git
commands) to end up with timestamps such that it always ran
MakeHeader.py but never used its output, leading to overbuild noise
when running what should be a null 'make'.
- but mostly: it's just an awkward way of dealing with C code.
