If using a new book, MAKEFLAGS is set to -j$(nproc), so that if
we want to easure timings with 4 processors and our computer has
more than that, we need to restrict the number of processors.
Jhalfs allows to do that using th cpuset cgroup controller, so that
it only restrits the make job and not the whole machine. For that
use a small scripts written by Xi Ruoyao that restarts make this
the cpuset set.
- Put parallelization menu first
- Fix the logic for variable definitions in this menu
- change jhalfs to reflect the separation of optimization and
parallelization
- validate new variables
- remove MAKEFLAGS from the validation of optimize variables
- also remove the black list, which has not been used in years.
- Replace the menu system with the Kconfiglib, which has an ISC license
- Remove farce and any reference to it
- Rewrite the copyright notice, add the LICENSE files
- Adapt Config.in and a few other programs to the new menu system

Improve testing of configuration file timestamp
* Provide a default value for each so that the comparisons of the time
of each file doesn't fail.
* Two commands in the Makefile could acceptably fail, but would
produce some ugly warnings.

* Various improvements from shellcheck around quoting, the use of
read, `` vs $() and other logical comparisons
* Provide a function for sourcing/loading files so we can remove a lot
of duplication. Move loading of some functions from
common/common-functions to ./jhalfs for consistency
* Provide some functions for standardized messaging
* Remove other duplication in the code, especially checking VERBOSITY
* Standardize indentation. Two spaces seemed the most prevalent so I
went with that.
Patch by Jeremy Huntwork, with slight modifications.
- add variables LOCAL (y is hw clock set to local time) and LOG_LEVEL (sysv)
- generate /etc/sysconfig/console (sysv) or /etc/vconsole.conf (systemd)
- generate /etc/adjtime (only systemd)
- remove UNICODE and FONTMAP variables (jhalfs makes unicode default)
With bash 5.0, a SIGCHLD signal is sent whenever a subshell exits. The signal
numbers passed to the trap instruction in jhalfs contain SIGCHLD, and this
new behavior causes jhalfs to exit. Fix this by using names instead of numbers
for the trap, and (of course) not trapping SIGCHLD.
- LFS_XML variable was forgotten in Config.in
- All customization to $JHALFSDIR have to be done before getting the
{H,C,}LFS book, so that custom/config/* has to be copied before getting
the book.
