Patchset related to array functions

[Daniel Llorens]

I propose this patchset to be merged in master. It is rebased on top of current 
master (867316ffcd65bd1e5e23813c22ba2515586ae845). I have pushed it as branch 
lloda-squash0 to savannah 
(http://git.savannah.gnu.org/gitweb/?p=guile.git;a=shortlog;h=refs/heads/lloda-squash0).

A summary:

* Enable typed arrays in (restricted-sort!), (sort!), (sort).

* New functions (array-from) (array-from*) (array-amend!) (array-for-each-cell) 
(array-for-each-cell) (array-for-each-cell-in-order), including documentation 
and tests.

* Some speed ups and removal of deprecated code.

* A minor bug fix in the compiler.

* Move to C99. Some of the patches above depend on this. Surely there's more to 
be done to take advantage of C99, but I don't think it's necessary to do it all 
in one patch, so I would ask that this be applied anyway. Otherwise, I'd prefer 
to rebase the patchset on top of any other enable-C99 patch.

Thanks,

        Daniel
