Hartmut Brandt 7a2029bac2 Clean up include files and file including. Split nonints.h into pieces 
that get included just where they are needed. All headers include the
headers that they need to compile (just with an empty .c file). Sort
includes alphabetically where apropriate and fix some duplicate commenting
for struct Job, struct GNode and struct Shell by removing one version and
inlining the comments into the structure declaration (the comments have been
somewhat outdated).

This patch does not contain functional changes (checked with md5).

* targ.c --
* Functions for maintaining the Lst allTargets. Target nodes are
* kept in two structures: a Lst, maintained by the list library, and a
* hash table, maintained by the hash library.
*
* Interface:
* Targ_Init Initialization procedure.
*
* Targ_NewGN Create a new GNode for the passed target
* (string). The node is *not* placed in the
* hash table, though all its fields are
* initialized.
*
* Targ_FindNode Find the node for a given target, creating
* and storing it if it doesn't exist and the
* flags are right (TARG_CREATE)
*
* Targ_FindList Given a list of names, find nodes for all
* of them. If a name doesn't exist and the
* TARG_NOCREATE flag was given, an error message
* is printed. Else, if a name doesn't exist,
* its node is created.
*
* Targ_Ignore Return TRUE if errors should be ignored when
* creating the given target.
*
* Targ_Silent Return TRUE if we should be silent when
* creating the given target.
*
* Targ_Precious Return TRUE if the target is precious and
* should not be removed if we are interrupted.
*
* Debugging:
* Targ_PrintGraph Print out the entire graphm all variables
* and statistics for the directory cache. Should
* print something for suffixes, too, but...
