Makefile: drop GEN_HDRS
When ebb7baf0 ("Makefile: add a hdr-check target", 2018-09-19)
implemented hdr-check target, it wanted to leave some header files
exempt from the stricter check the target implements, and added
GEN_HDRS macro.
This however is probably a bad move for two reasons:
- If we value the header cleanliness check, we eventually want to
teach our header generating scripts to produce clean headers.
Keeping the blanket "generated headers can be left as dirty as we
want" exception does not nudge us in the right direction.
- There is a list of generated header files, GENERATED_H, which is
used to keep track of dependencies. Presence of GEN_HDRS that is
too similarly named would confuse developers who are adding new
generated header files which list to add theirs.
- Even though unicode-width.h could be generated using a contrib/
script, as far as our build infrastructure is concerned, it is a
source file that is tracked in the source control system. Its
presence in GEN_HDRS list is doubly misleading.
Get rid of GEN_HDRS, which is used only once to list the headers we
do not run hdr-check test on, and instead explicitly list that the
ones, either tracked or generated, that we exempt from the test.
This allows GENERATED_H to be the sole "here are build artifact
header files that are expendable" list, so use it in the clean
target to $(RM) them.

Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals.
Git is an Open Source project covered by the GNU General Public License version 2 (some parts of it are under different licenses, compatible with the GPLv2). It was originally written by Linus Torvalds with help of a group of hackers around the net.
Please read the file INSTALL for installation instructions.
Many Git online resources are accessible from https://git-scm.com/ including full documentation and Git related tools.
See Documentation/gittutorial.txt to get started, then see Documentation/giteveryday.txt for a useful minimum set of commands, and Documentation/git-<commandname>.txt for documentation of each command. If git has been correctly installed, then the tutorial can also be read with man gittutorial or git help tutorial, and the documentation of each command with man git-<commandname> or git help <commandname>.
CVS users may also want to read Documentation/gitcvs-migration.txt (man gitcvs-migration or git help cvs-migration if git is installed).
The user discussion and development of Git take place on the Git mailing list -- everyone is welcome to post bug reports, feature requests, comments and patches to git@vger.kernel.org (read Documentation/SubmittingPatches for instructions on patch submission). To subscribe to the list, send an email with just “subscribe git” in the body to majordomo@vger.kernel.org. The mailing list archives are available at https://lore.kernel.org/git/, http://marc.info/?l=git and other archival sites.
Issues which are security relevant should be disclosed privately to the Git Security mailing list git-security@googlegroups.com.
The maintainer frequently sends the “What's cooking” reports that list the current status of various development topics to the mailing list. The discussion following them give a good reference for project status, development direction and remaining tasks.
The name “git” was given by Linus Torvalds when he wrote the very first version. He described the tool as “the stupid content tracker” and the name as (depending on your mood):
