Clean up some of the bitrot affecting the CANNOT_DUMP code. This lets the build succeed again, and fixes the testing framework so that most test cases now pass. About twenty test cases still fail, though, and we still have Bug#24974. * configure.ac (CANNOT_DUMP): Now empty if CANNOT_DUMP. (SYSTEM_MALLOC): Now true if CANNOT_DUMP. There should no longer be any point to messing with a private memory allocator unless Emacs is dumping. * src/alloc.c (alloc_unexec_pre, alloc_unexec_post, check_pure_size): * src/image.c (reset_image_types): * src/lastfile.c (my_endbss, _my_endbss, my_endbss_static): Do not define if CANNOT_DUMP. * src/emacs.c (might_dump) [CANNOT_DUMP]: Now always false and local. (daemon_pipe) [!WINDOWSNT]: Now static. * test/Makefile.in (mostlyclean): Remove *.tmp files. (make-test-deps.mk): Elide CANNOT_DUMP chatter.

### Commentary:
|
|
|
|
## Some targets:
|
|
## check: re-run all tests, writing to .log files.
|
|
## check-maybe: run all tests which are outdated with their .log file
|
|
## or the source files they are testing.
|
|
## filename.log: run tests from filename.el(c) if .log file needs updating
|
|
## filename: re-run tests from filename.el(c), with no logging
|
|
|
|
