Christian Prochaska 0fd53c7fe4 Extract numeric string arguments with the correct signedness
There are lots of places where a numeric argument of an argument string
gets extraced as signed long value and then assigned to an unsigned long
variable. If the value in the string was negative, it would not be
detected as invalid (and replaced by the default value), but become a
positive bogus value.

With this patch, numeric values which are supposed to be unsigned get
extracted with the 'ulong_value()' function, which returns the default
value for negative numbers.

Fixes #1472

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.
