[SV 63347] Always add command line variable assignments to MAKEFLAGS
This commit introduces two visible changes:
1. Keep command line variable assignments in MAKEFLAGS at all times,
even while parsing makefiles.
2. Define makeflags immediately when a makefile modifies MAKEFLAGS.
The new MAKEFLAGS and MAKEOVERRIDES initialization procedure:
1. decode_switches (argc, argv, o_command) is called to parse command
line variable assignments.
2. Command line variable assignments go through quote_for_env.
Initialize -*-command-variables-*- to the quoted values.
3. MAKEOVERRIDES is initialized to refer to -*-command-variables-*-
with origin o_env to keep the definitions in the database intact.
4. define_makeflags() is called which adds MAKEOVERRIDES to MAKEFLAGS.
5. Makefiles are parsed. If a makefile modifies MAKEFLAGS, the new
value of MAKEFLAGS is defined right away.
6. Env switches are decoded again as o_env. The definitions set by
decode_switches at step 1 stay intact, as o_command beats o_env.

failure cases; for example:
$ cat makefile
all:; $(hello)
$ make hello='$(world'

Rework temp file handling to avoid GNU libc warnings
Original patch provided by Paul Eggert <eggert@cs.ucla.edu>.
GNU libc will generate a link-time warning if we use mktemp() even
though we are using it safely (we only use it with mkfifo()).
Avoid this and clean up some handling.
First, check all calls related to temporary files and exit with a
fatal error and a useful message if we can't obtain them. In some
situations it might be possible to continue with reduced capability
but it's not worth the effort.
On POSIX systems we can create anonymous temp files using O_TMPFILE
if it's supported, else if we're using the default location and we
have dup(2), we can use standard tmpfile() and get an FD from it.
If we need a named temp file and FILE* and we have mkstemp() we can
use that, else if we have fdopen() we can get a temp FD and open it.
If none of those are available all we can do is generate a temp name
then open it with fopen() which is not secure.
* src/makeint.h (get_tmpdir): Declare it for use elsewhere.
* src/misc.c (get_tmpdir): Make it public not static.
(get_tmptemplate): Simplify the implementation.
(get_tmppath): Only define this if we have to have it to avoid
warnings from GNU libc.
(get_tmpfd): Generate fatal errors on error.
(get_tmpfile): Ditto. Open files in "wb+" mode to match tmpfile().
Require a filename pointer (all callers want it).

errors. Instead construct the FIFO name based on the PID.
(osync_setup): get_tmpfd() can't fail so don't check it.
(os_anontmp): If the system supports O_TMPFILE use it. If not, and
we want to create the temporary file in the default directory, we
can use tmpfile() then use dup() to copy the file descriptor.
* src/main.c (main): get_tmpfile() can't fail.
