Check the ctx argument of the memory macros
Isl defines its own set of memory management macros. These macros currently
expect an isl_ctx*, but do not yet actively use it. Hence, it is possible to
pass a random string to these macros, without the compiler issuing any warnings.
And in case an isl_ctx* is passed, the compiler does not count the macro call
as a valid use, which may lead to some unexpected 'variable never used'
warnings.
We solve this, by adding a compile time check that always verifies that ctx has
the type isl_ctx*. This is also a valid use of ctx and consequently stops the
'variable never used' warnings. The check itself is designed such that it will
be optimized out during compilation.
While at this fix all cases, where some invalid structures were passed to the
memory location macros instead of an valid isl_ctx*.

Remove use of PATH_MAX
Instead of using statically allocated char arrays, allocate the memory for the

scheduling: optionally split parallel rows in non-tilable bands
If a scheduling row that is constructed to carry dependences
is of the form, say, { S1[..] -> [2 * g(..)]; S2[..] -> [2 * g(..) + 1] },
then it is usually better to split off the constant term into a separate
band and obtain { S1[..] -> [g(..),0]; S2[..] -> [g(..),1] } instead.
In particular, the code generated from the second schedule is usually
simpler than that from the first schedule.

scheduling: optionally create schedules with outermost parallelism
Some applications require not only tilable bands, but also parallel
loops inside those bands. The default algorithm favors larger bands
over having parallel loops inside the band. It is always possible
to sacrifice one of the loops in the band to create parallelism by
applying a wavefront transformation. This typically leads to more
complicated schedules, however.
Instead, when enabled, we now force there to be at least one parallel
loop inside each tilable band.

configure.ac: use non-deprecated form of AM_INIT_AUTOMAKE
The old form was deprecated back in automake 1.6, so it's probably
about time to switch.
The new form allows us to specify automake options, which in turn
allows us to use "autoreconf -i" instead of the current autogen.sh script.
This is especially useful for OS X users. OS X comes with its own
libtool, which is different from GNU's. GNU libtool is therefore
usually made available as glibtool and libtoolize as glibtoolize.
The current autogen.sh script therefore does not work as is for those users.
autoreconf would have the same problem, except that the macport version
of autoconf has a pathed version of autoreconf which looks for
glibtoolize instead of libtoolize.

add isl_{basic_,}map_may_be_set
Sets and maps share the same internal representation, but only
some of those internal representations can be sets.
Add specific functions to test this condition, replacing some
open coded variants.

add isl_aff
Affine expressions will be used in a subsequent commit to specify
the objective function for an ILP problem, but they should hopefully
be more generally useful.

isl_polynomial.c: move merge_divs to isl_local_space.c
In time, we will want to define isl_qpolynomials over isl_local_spaces.
We start by moving some of the handling of divs to isl_local_space.c
as it also useful for local spaces in general.
The merging is adapted to handle possibly unknown divs, which should
never be merged.

add isl_local_space
Local spaces should hopefully replaced the duplicate functionality
in basic sets and quasi-polynomials.
In a later commit, we will start by using it in affine expressions.
