sommerfeld bcb141e5d0 Reuse the Hash_Entry `name' field to store the variable name when we
can (i.e., everything except environment variables, which aren't
stored in hash tables).

While we're here, inline the body of VarDelete into Var_Delete since
it's the only caller and it's just simpler that way when v->name can
share storage with the hash entry and may not need to be freed
separately.

Speeds up the infamous libc build benchhmark maybe 1% on PIII, 4% on
alpha pc164

Suggested by Perry Metzger.

mycroft d2ec8b0e26 Replace the linear variable list in the GNode with a hash table. Gives a
small (~10% on my machine) speedup building libc.

christos f46f2d693e PR/5210: Hauke Fath: make core dumps with .SHELL
Unfortunately this revealed a deeper problem with the brk_string code.
To fix it:
	- remove sharing of the buffer between brk_string invocations
	- change the semantics of brk_string so that the argument array
	  starts with 0, and return the buffer where the strings are
	  stored

christos e2d4e7ccc8 PR/3825: David A. Holland: global regexp handling gets stuck in infinite loop.
Actually there were two bugs:
	- Add REG_NOTBOL after the first substitution.
	- Handle the rm_so == rm_eo == 0 case, where in a substitution such
	  as 's/bzzzt/z*/g' the first time z* matches nothing.

christos 8819044d2a [initial version of the substitution/regexp changes were courtesy of Der Mouse]
- fix the variable substitution code in make [PR/2748]
      1. change s/a/b/ so that it substitutes the first occurance of the
	 pattern on each word, not only the first word.
      2. add flag '1' to the variable substitution so that the substitutions
	 get performed only once.

  ***THIS IS AN INCOMPATIBLE CHANGE!***

  Unfortunately there was no way to make things consistent without
  modifying the current behavior. Fortunately none of our Makefiles
  depended on this.

	    OLD:

		VAR      = aa1 aa2 aa3 aa4

		S/a/b/   = ba1 aa2 aa3 aa4
		S/a/b/g  = bb1 bb2 bb3 bb4

	    NEW:

		VAR      = aa1 aa2 aa3 aa4

		S/a/b/   = ba1 ba2 ba3 ba4
		S/a/b/1  = ba1 aa2 aa3 aa4
		S/a/b/g  = bb1 bb2 bb3 bb4
		S/a/b/1g = bb1 aa2 aa3 aa4

- add regexp variable substitution via 'C/foo/bar/' [PR/2752]

- add variable quoting via the ${VAR:Q} modifier. This is useful when running
  recursive invocations of make(1):

	make VAR=${VAR:Q}

  will always work... (This may prove useful in the kernel builds...) [PR/2981]

christos 61067003d8 Minor:
- ${.PREFIX} should never contain a full pathname
    - Fixed gcc -Wall warnings
Major:
    - compatMake is now FALSE. This means that we are now running in
      full pmake mode:
	  * rules on dependency lines can be executed in parallel and or
	    out of sequence:

	    foo: bar baz

	    can fire the rule for baz before the rule for bar is fired.
	    To enforce bar to be fired before baz, another rule needs to be
	    added. [bar: baz]
	  * adjacent shell commands in a target are now executed by a single
	    invocation of the shell, not one invocation of the shell per line
      (compatMake can be turned off using the -B flag)
    - The -j flag now works... I.e. make -j 4 will fork up to four jobs in
      parallel when it can. The target name is printed before each burst
      of output caused by the target execution as '--- target ---', when j > 1
    - I have changed all the Makefiles so that they work with make -j N, and
      I have tested the whole netbsd by:
	  'make -j 4 cleandir; make -j 4 depend; make -j 4; make -j 4 install'
    - I have not compiled or tested this version of make with -DREMOTE.
