    build.sh: extract tarballs in a consistent location
    
    The tarballs are extracted in the same location where they are found. So libXi
    code will be extracted in the toplevel directory if this is where the tarball
    is found. Then lib/libX11 code will be extracted under lib subdir if, for
    example, the tarball is placed in the lib subdir.
    
    This patch promotes a consistent build structure based on what we see when
    working in git. The source code for modules having components (e.g. app,
    driver) is extracted under the module directory. For modules with no
    components (e.g. xserver), the tar file is extracted under the toplevel
    directory. This is done regardless of where the tarball is found, either
    in the toplevel directory, or under the module directory.
    
    Sample build directory hierarchy:
    app/luit-1.1.1
    driver/xf86-input-void-1.4.0
    font/font-util-1.3.0
    lib/libXi-1.7
    mesa/libdrm-2.4.47
    mesa/Mesa-9.2.1
    pixman-0.30.2
    xcb/libxcb-1.9
    xcb/xcb-proto-1.8
    xkeyboard-config-2.5
    xorg-server-1.14.99.2

    build.sh: tarballs not found under their respective module directory
    
    Currently, the module name is changed to add a subdir. For example "xcb" is
    changed to "xcb/proto". The tarball cannot be found under xcb as expected.
    This is done for pixman, xcb and mesa only, not for app, driver, lib, or any
    other module which is inconsistent.
    
    Moving the tarball under xcb/proto works, but yields a build structure
    that is unpractical: xcb/proto/xcb-proto-1.8. The source code is now
    under two subdirs rather than the usual one.
    
    The package archive already contains the component directory, suffixed
    with a version number.
    
    By not changing the module name, we have xcb/xcb-proto-1.8. The same
    pattern holds true for mesa and pixman. Changing the module name has
    other adverse effects in subsequent functionality.
    
    Note that for pixman, this module is under the "pixman" directory
    and is not a component of the "lib" module. The module directory
    structure is given by git and not by the location of the tarballs
    on the web.

    build.sh: complete error path when extracting from tars
    
    The return code was not checked and the script aborts if the tar command
    fails rather processing the errors in the usual manner.

    build.sh: recover SRCDIR when tar command fails
    
    The SRCDIR is changed before running the tar command. If it fails,
    the calling function attempts to cd to the directory the tar command
    was not successful in creating.

    build.sh: add support for the xz archive file format
    
    There is one non-xorg project (libevdev) upon which xorg depends
    that is using this format. Most likely others will follow.

    build.sh: no longer require a trailing slash for module name
    
    A few modules have a single level directory such as pixman, xserver,
    and so on. Currently the script requires specifying such modules in
    the module list file or with the -o option with a trailing slash. So one needs
    to learn and remember using pixman/ or xserver/.
    
    The patch will correct the situation such that both input are accepted.
    The generated list (-L option) will write the module names without the
    trailing slash.
