Generate C/C++ code for the XS initializer function.

perl -MExtUtils::Embed -e xsinit -- -o xsinit.c Socket
This will generate code with an B<xs_init> function that glues the perl B<Socket::bootstrap> function
-to the C B<boot_Socket> function and writes it to a file named "xsinit.c".

Note that B<DynaLoader> is a special case where it must call B<boot_DynaLoader> directly.
When looking for B<DBD::Oracle> relative to a search path,
we should find B<auto/DBD/Oracle/Oracle.a>

In addition, when ModuleName.a is found, additional linker arguments

This will do the same as the above example, along with printing additional arguments for linking with the B<Socket> extension.
For including perl header files this function simply prints:
- -I$Config{archlib}/CORE
+ -I$Config{archlibexp}/CORE
So, rather than having to say:
- perl -MConfig -e 'print "-I$Config{archlib}/CORE"'
+ perl -MConfig -e 'print "-I$Config{archlibexp}/CORE"'
Just say:
B<xsinit()> uses the xsi_* functions to generate most of it's code.
