Cygwin: CI configuration update
Install autoconf and automake, and run winsup/autogen.sh, and don't have
it silently ignore failures.

On AppVeyor:
- use latest VM image, to reduce time spent installing updates.
- run the testsuite, but ignore the result, as some tests don't work
correctly.
- hardcode the python-lxml and python-ply packages to install, so we get
ones for the right python.
- install texlive collections now needed to build documentation.

On github:
- Use a copr for cocom, since RPMSphere's package updates don't track
fedora:latest very efficently.

Corinna Vinschen 456c3a4638 Cygwin: path_conv: Try to handle native symlinks more sanely
For local paths, add a check if the inner path components contain native
symlinks or junctions.  Compare the incoming path with the path returned
by NtQueryInformationFile(FileNameInformation).  If they differ, there
must be at least one native symlink or junction in the path.  If so,
treat the currently evaluated file as non-existant.  This forces
path_conv::check to backtrack inner path components until we eliminated
all native symlinks or junctions and have a normalized path.

Corinna Vinschen 183e5f0a15 Cygwin: take hypotl function from Mingw-w64
The simple newlib hypotl for real long double architectures is too
simple at this point.  It's implemented as a real call to sqrtl(x^2+y^2).
This has a fatal tendency to overflow for big input numbers.  Hypotl
isn't supposed to do that if the result would still be valid in range of
long double.

Given the complexity of implementing hypotl for various architectures,
we just take the hypotl function from Mingw-w64, which is in the public
domain.

Even though this hypotl is an architecture-independent implementation,
we can't use it for newlib yet, unfortunately, because it requires logbl
under the hood.  Logbl is yet another function missing in newlib for
real long double architectures.

Corinna Vinschen 80bd01ef83 Add build mechanism to share common header files between machines
So far the build mechanism in newlib only allowed to either define
machine-specific headers, or headers shared between all machines.
In some cases, architectures are sufficiently alike to share header
files between them, but not with other architectures.  A good example
is ix86 vs. x86_64, which share certain traits with each other, but
not with other architectures.

Introduce a new configure variable called "shared_machine_dir".  This
dir can then be used for headers shared between architectures.

Johannes Schindelin 0631c6644e Cygwin: Treat Windows Store's "app execution aliases" as symbolic links
When the Windows Store version of Python is installed, so-called "app
execution aliases" are put into the `PATH`. These are reparse points
under the hood, with an undocumented format.

We do know a bit about this format, though, as per the excellent analysis:
https://www.tiraniddo.dev/2019/09/overview-of-windows-execution-aliases.html

	The first 4 bytes is the reparse tag, in this case it's
	0x8000001B which is documented in the Windows SDK as
	IO_REPARSE_TAG_APPEXECLINK. Unfortunately there doesn't seem to
	be a corresponding structure, but with a bit of reverse
	engineering we can work out the format is as follows:

	Version: <4 byte integer>
	Package ID: <NUL Terminated Unicode String>
	Entry Point: <NUL Terminated Unicode String>
	Executable: <NUL Terminated Unicode String>
	Application Type: <NUL Terminated Unicode String>

Let's treat them as symbolic links. For example, in this developer's
setup, this will result in the following nice output:

	$ cd $LOCALAPPDATA/Microsoft/WindowsApps/

	$ ls -l python3.exe
	lrwxrwxrwx 1 me 4096 105 Aug 23  2020 python3.exe -> '/c/Program Files/WindowsApps/PythonSoftwareFoundation.Python.3.7_3.7.2544.0_x64__qbz5n2kfra8p0/python.exe'

Johannes Schindelin 2533912fc7 Cygwin: Allow executing Windows Store's "app execution aliases"
The Windows Store version of Python (and apparently other Windows Store
applications) install a special reparse point called "app execution
alias" into the user's `PATH`.

These applications can be executed without any problem, but they cannot
be read as if they were files. This trips up Cygwin's beautiful logic that
tries to determine whether we're about to execute a Cygwin executable or
not: instead of executing the application, it will fail, saying
"Permission denied".

Let's detect this situation (`NtOpenFile()` helpfully says that this
operation is not supported on this reparse point type), and simply skip
the logic: Windows Store apps are not Cygwin executables (and even if
they were, it is unlikely that they would come with a compatible
`cygwin1.dll` or `msys-2.0.dll`).

This fixes https://github.com/msys2/MSYS2-packages/issues/1943
