4792e154b6 Convert to auto-generated ChangeLog files.
Rename existing ChangeLog files so they won't be distributed.
Add targets to maintMakefile to generate ChangeLog from the Git
repository.  This will require a version of gnulib be available.
Because ChangeLog is auto-generated, we have to switch our
automake mode to "foreign" or it will complain and fail.

2fb91e19a0 Sanitize the registered function interface.
Expand the characters which are legal in a function name, and check
the name for validity.  Create a type for the function pointer.
Convert the last argument from a boolean to flags, to allow for expansion.

543521cd47 Reset GNUMAKEFLAGS after parsing.
If we don't do this we'll continually add flags on recursion.  This
is mainly for users to set in their environment before invoking make.

deff9dacc9 Enhance the output sync mode.
Create a new file, output.c, and collect functions that generate output there.
We introduce a new global context specifying where output should go (to stdout
or to a sync file), and the lowest level output generator chooses where to
write output based on that context.

This allows us to set the context globally, and all operations that write
output (including functions like $(info ...) etc.) will use it.

Removed the "--trace=dir" capability.  It was too confusing.  If you have
directory tracking enabled then output sync will print the enter/leave message
for each synchronized block.  If you don't want that, disable directory
tracking.

c7732bd5ad Add a new variable: GNUMAKEFLAGS
This allows you to write portable makefiles that set GNU make-specific command
line options in the environment or makefile: add them to GNUMAKEFLAGS instead
of MAKEFLAGS and they will be seen by GNU make but ignored by other
implementations of make.

381baeef7a Add new --trace[=MODE] flags, with --trace=dir
This mode replaces the previous heuristic setting enabled with -O, where we
would log directory enter/leave for each synchronized output.  Now we only
do that if --trace=dir is given.

3484c9675a Add memory allocation cleanup to loadable objects.
Add gmk_alloc() and gmk_free() functions so loadable objects can access our
memory model.  Also provide a more extensive example in the manual.

7f01830927 Add support for per-job output sync.
A new flag to the -O/--output-sync, "job", selects a per-job (that is, per
line of a recipe) output synchronization.  To support this move the close of
the temp file out of the sync_output() function and don't do it until we free
the child, since we may call sync_output() multiple times in a given recipe.
When we set up for a new temp file, if we're in per-job mode we truncate the
file and seek to the beginning to re-use it for every job.

5058a94ee7 Expand the loadable object support.
Provide a simple API for loaded objects to interact with GNU make.  I still
won't guarantee that this API won't change but it's much closer to something
that's supported and provides easy-to-use interfaces with a public header
file.

88f1bc8b55 Modify backslash/newline handling for POSIX.
We fixed Savannah 16670 but that broke previously-working makefiles
that relied on the GNU make behavior.  The POSIX behavior doesn't
seem to me to be better, and can be obtained using GNU make as well,
so put it back as the default behavior and require .POSIX to
get the POSIX behavior.
Add a new section to the manual discussing backslash/newline handling.
Update the test suite.

as GNU make's ":=", so add support for this new operator.

c992c4d80f Add GNU Guile as an optional embedded scripting language for make.
On configure-enabled systems, configure will detect Guile installed
(using pkg-config, which is how GNU Guile is distributed) and enable
it if so.

On all non-configure-enabled systems, currently, the default is for
Guile support to be disabled.
