Sebastian Sumpf ad70160847 LWIP: Fix dead lock in semaphore back-end
Make sure unlock is called when 'global_mutex' reaches zero count. Add verbose
variable in order to disable some output. Disable irritating 'Overflow' messages
in 'sys_mbox_post' and 'sys_mbox_try_post' per default. This may happen and is
not an error, since the ring buffer is full and will be emptied eventually.
Remove priority from genode_org run script.

Should fix #347

Usage
-----

At the root of the 'libports' repository, there is 'Makefile' automating the
task of downloading and preparing the library source codes. By just typing
'make', you get an overview of the available libraries and further
instructions.

In the common case, you might just want to prepare all packages by issuing:
! make prepare

Alternatively, you can select individual packages to prepare by specifying
their base names (without the version number) as command-line argument. For
example, the following command prepares both the C library and the Freetype
library:
! make prepare PKG="libc freetype"

After having prepared the 'libports' repository, you are ready to include the
repository into the build process by appending it to the 'REPOSITORIES'
declaration of your '<build-dir>/etc/build.conf' file.


Under the hood
--------------

For each library, there is a file contained in the 'libports/ports/'
subdirectory. The file is named after the library and contains the
library-specific rules for downloading the source code and installing header
files.


How does 'libports' relate to the other repositories?
-----------------------------------------------------

Most libraries hosted in the 'libports' repository expect a complete C library,
which is provided with the 'libc' package. Please do not forget to prepare the
libc package when using any of the other libports packages. The libc, in turn,
depends on the 'os' repository for its back end. Because the 'os' repository is
the home of the dynamic linker, libraries contained in 'libports' are safe to
assume the presence of the dynamic linker and, thus, should be built as shared
libraries.
