Changes of interest

o unit-tests: use private TMPDIR to avoid errors from other users
o avoid strdup in mkTempFile
o always use vfork
o job.c: do not create empty shell files in jobs mode
reduce unnecessary calls to waitpid
o cond.c: fix debug output for comparison operators in conditionals

Quite a lot of churn on style, but lots of

Some interesting entries from ChangeLog

o .MAKE.{UID,GID} represent uid and gid running make.

o allow env var MAKE_OBJDIR_CHECK_WRITABLE=no to skip writable

variable parse errors.

Update to bmake-20201101

Lots of new unit-tests increase code coverage.

Lots of refactoring, cleanup and simlpification to reduce
code size.

Fixes for Bug 223564 and 245807

Updates to dirdeps.mk and meta2deps.py

Update to bmake-20200902

Lots of code refactoring, simplification and cleanup.
Lots of new unit-tests providing much higher code coverage.

Other significant changes:

o new read-only variable .SHELL which provides the path of the shell
used to run scripts (as defined by the .SHELL target).

o variable parsing detects more errors.

o new debug option -dl: LINT mode, does the equivalent of := for all
variable assignments so that file and line number are reported for
variable parse errors.

Key changes include reduced noise at end of failed build log

MFV r359442: bmake: import -fno-common fix build back from upstream

sjg@ committed the local patch previously committed upstream; pull it in to
vendor/ to ease any potential stress of future imports.

bmake: fix -fno-common build

debug was declared extern, but debug_file was not; correct this and define
debug_file in main.c (as debug is) to fix the -fno-common build.

-fno-common will become the default with GCC10/LLVM11.

Move the call to Job_SetPrefix() to Job_Init() so that
makefiles have had a chance to set .MAKE.JOB.PREFIX

Merge bmake-20130730
Main feature of interest is .MAKE.JOB.PREFIX=
to suppress --- job --- tokens.

We really need to get the bsd.own.mk from this tree so the
correct options are set.
Also defined NO_PWD_OVERRIDE to match behavior of fmake.
