Remove conditions for HOST_PLATFORM=msys.

It never really worked beyond the most basic of commands
and required a lot of hacks, and these days WSL should be used instead.

configure & build: Add basic support for building with MSYS.

Also remove the MINGW support, as it was far too incomplete.

This *should* work under case-sensitive NTFS, but instead,
it seems #14963 occurs. So perhaps there is a GCC bug
related to case-sensitive vs. case-insensitivity after all.

Add more robust generic attribute emulation variant

The new configure option "--use-xattr-ref" enables an xattr assisted
variant of the generic attribute emulation. Instead of using the inode
ID of a node to identify its attribute directory, we use a reasonably
unique random 128 bit number, which we generate and attach as an
attribute to the node. This way, when a node changes its inode ID
(defragmentation?) or the inode ID of a removed node with a left-over
attribute directory is reused, attributes won't get mixed up.

The old method is still used for symlinks (since on Linux only
priviledged users can write attributes on symlinks), but those usually
only have a rather boring BEOS:TYPE attribute, so mix-ups wouldn't be
that problematic anyway.

Fix build without xattrs being used

* need to invoke fs_fopen_attr() instead of fs_open_attr()

Build fix part 1: update generic fs-attr code

Open/close attribute support for xattrs backend

For the xattr/BSD (untyped) attribute backend implement fs_fopen_attr()
and fs_close_attr(). A new AttributeDescriptor is created. It is
currently used in write_pos() only.

Generic attribute emulation: Export function __get_attribute_dir_path()

* Removed the BUILDING_FS_SHELL guarded code. It was needed for the old
FS shell only.
* Accessing attributes of symlinks was broken.

Under Linux it is now possible to emulate the BeOS attribute support via
xattrs. It can be enabled with the configure switch "--use-xattr". Note
that the amount of data stored in attributes may be limited by the used
file system -- e.g. AFAIK ext3 has a limit of one block (usually 4 KB)
for all attributes of a file, which might not suffice. XFS should be
fine, as should ReiserFS 3.6 (or any FS which stores attributes in
hidden files).
