69f23174d3 Use Gnulib's `strftime' to address bug #24130. 
* libguile/stime.c (scm_strftime): Use `nstrftime ()' from Gnulib.
  This provides the same semantics on all platforms, thereby fixing
  bug #24130.

* doc/ref/posix.texi (Time): Remove note about non-portable `%Z'
  behavior.  Describe the new, portable behavior.

* test-suite/tests/time.test ("strftime")["strftime %Z doesn't return
  garbage"]: Reinstate.
  ["C99 %z format"](have-strftime-%z): Remove.
  ("GMT", "EST+5"): Don't use `have-strftime-%z'.

40945e5e9f Add a statistic for tracking how many cells are marked conservatively. 
This allows an informed choice for deciding how many segments to
create.  After startup, ~2% of the cells are scanned conservatively.

82ae1b8eb3 Garbage collection cleanup. 
* New file gc-segment-table.c: hold code for the segment table.

* Remove data that might be out of date; remove
  scm_i_adjust_min_yield().  We don't store min_yields, since they
  are only accurate at one point in time (when the sweep finishes). 
  We decide the min yield at that point from min_yield_fraction and
  freelist->collected / freelist->swept

* Introduce scm_i_gc_heap_size_delta() replacing
  scm_i_gc_grow_heap_p().
  
* Remove foo_1 fields containing penultimate results.

* After GC, count mark bit vector to discover number of live
  objects. This simplifies hairy updates.

* Many formatting and layout cleanups.

* Fix in scm_i_sweep_card(): return the length of free_list returned,
  rather than number of deleted objects.

* For mtrigger GCs: do not also run a full sweep after the gc() call, as
  this is inconsistent with lazy sweeping.

* Remove scm_i_make_initial_segment().

* Use calloc in scm_i_make_empty_heap_segment() to save on
  initialization code.

* New function scm_i_sweep_for_freelist() which sweeps, with proper
  statistic variable updates.

* New segments are conceptually blocks with 100% reclaimable cells.

* Remove some useless constants/comments: SCM_HEAP_SIZE,
  SCM_INIT_HEAP_SIZE, SCM_EXPHEAP, SCM_HEAP_SEG_SIZE

* Do not increment scm_cells_allocated() from the
  scm_[double]cell(). This would be a race condition.

* Move some deprecation checks in separate functions to not distract
  from main code flow.

091baf9edf Single stepping through code from Emacs 
When you use GDS to evaluate Scheme code from Emacs, you can now use
`C-u' to indicate that you want to single step through that code. See
`Evaluating Scheme Code' in the manual for more details.

	* scheme-using.texi (Evaluating Scheme Code): Document use of
        `C-u' prefix with evaluation commands.

        * gds-scheme.el (gds-eval-region, gds-eval-expression)
        (gds-eval-defun, gds-eval-last-sexp): Support `C-u' prefix,
        meaning that user wants to single step through the code.

        * gds-client.scm (handle-nondebug-protocol): Add support for
        setting a trap on code that is about to be evaluated.
