This patch hails from Git for Windows (where the Cygwin runtime is used
in the form of a slightly modified MSYS2 runtime), where it is a
well-established technique to let the `$HOME` variable define where the
current user's home directory is, falling back to `$HOMEDRIVE$HOMEPATH`
and `$USERPROFILE`.
The idea is that we want to share user-specific settings between
programs, whether they be Cygwin, MSYS2 or not. Unfortunately, we
cannot blindly activate the "db_home: windows" setting because in some
setups, the user's home directory is set to a hidden directory via an
UNC path (\\share\some\hidden\folder$) -- something many programs
cannot handle correctly, e.g. `cmd.exe` and other native Windows
applications that users want to employ as Git helpers.
The established technique is to allow setting the user's home directory
via the environment variables mentioned above: `$HOMEDRIVE$HOMEPATH` or
`$USERPROFILE`. This has the additional advantage that it is much
faster than querying the Windows user database.
Of course this scheme needs to be opt-in. For that reason, it needs
to be activated explicitly via `db_home: env` in `/etc/nsswitch.conf`.

setup >=2.925 indicates to postinstall and preremove scripts the Start
Menu suffix to use via the CYGWIN_START_MENU_SUFFIX env var.
It also indicates, via the CYGWIN_SETUP_OPTIONS env var, if the option
to disable Start Menu shortcut creation is supplied.
Update the Cygwin documentation postinstall and preremove scripts to
take these env vars into consideration.
So far locale(1) had to have knowledge how to construct, thus
duplicating the effort how Cygwin handles locale strings.
Move locale list and codeset list generation into Cygwin by
providing /proc/codesets and /proc/locales files. /proc/locales
does not list aliases, those are still handled in locale(1).
locale(1) opens the files and ueses that info for printing,
like any other application can do now.

Rather than guessing, based on just the presence of libbfd, add an
explicit configuration option, to build dumper or not, defaulting to
building it.
This might have some use when bootstrapping Cygwin for a new
architecture, or when building your own Cygwin-targetted cross-compiler,
rather than installing one from the copr, along with the dependencies of
libbfd.
Using ulinks here makes the result work on cygwin.com only, while
xrefs to FAQs are creating realtive links. Add xreflabel where
appropriate.

Originally the code was written to allow three ways of prefixing
accounts and to freely define a domain/account separator. This code
has been disabled even before being officially released, and it was
never re-enabled. Given there has been no complaints for eight years
now, drop this code eventually. Just add a macro to define the
domain/account separator statically.

Define FD_SETSIZE (<sys/select.h>) to be 1024 by default, and define
NOFILE (<sys/param.h>) to be OPEN_MAX (== 3200) by default.
Remove the comment in <sys/select.h> that FD_SETSIZE should be >=
NOFILE.
Bump API minor.

This reverts commit 1f8f7e2d54, "* libc/stdio/refill.c (__srefill):
Try again after EOF on Cygwin." If EOF is set on a file, the stdio
input functions will now immediately return EOF rather than trying
again to read. This aligns Cygwin's behavior to that of Linux.

A recent patch fixed gmondump to stop printing "0x0x" as an address
prefix. It turns out the Cygwin User's Guide and the gmondump and
ssp man pages (all from utils.xml) have examples of the same error.
Unless make is invoked with V=1, have xmlto pass the parameter
'man.output.quietly=1' to xsltproc to suppress "Note: Writing foo.N"
output from the manpages stylesheet.
Unless make is invoked with V=1, have xmlto pass the parameter
'chunk.quietly=1' to xsltproc to suppress "Writing foo.html for
sect1(foo)" output from the chunker.xsl stylesheet.
Unless make is invoked with V=1, have xmlto pass '-q' to dblatex when
building PDFs, to supress repeated "default template used in
programlisting or screen" warnings from dblatex's verbatim.xsl
stylesheet.
Drop mention of 32-bit installer, since it's offically discouraged, and
planned to be dropped soon.
Adjust various references to be something more generic, like 'the Cygwin
Setup program' to accommodate this.
Add patch, and make cocom unconditional in list of build prerequisites.
Even though the products of these tools are checked in, these tools are
required when building in a fresh git checkout, presumably due to the
order in which git creates the files resulting in timestamps which
indicate that the output of rules using these tools are older than
the inputs.

Also drop a duplicate sentence about 'fetch sources from git'.
Add a configure option '--disable-doc' to disable building of the
documentation by the 'all' target.
Check for the required tools at configure time, and require them if
building documentation is enabled.
Even if building the documentation was diabled with '--disable-doc',
'make -C doc' at the top-level can still make the documentation, if the
documentation tools were found. If the tools were not found, 'missing'
is used to issue a warning about that.
Update instructions for building Cygwin appropriately.
(Building documentation remains the default to increase the chances of
noticing when building the documentation is broken.)
The doc for gmondump says 1 or more FILENAME are expected, but 0 is
handled. That's an oversight. Make invocation with 0 FILENAMEs print a
one-line help message.
Reword the beginning of profiler's description doc to clarify target's
child processes are run but only optionally profiled.
