Support unpinned ibts

See merge request allzp/zipr!12

Resolve "probNog has non-determinism and doesn't always work"

Closes #11

See merge request allzp/zipr!13

Make sure that Zipr does not produce segments with RWX permissions.

Closes #8

See merge request allzp/zipr!11

Use copy_if and max_element rather than for loops.

Fixes #8. This will match the gap-filling scoop's perms
with those of the adjacent scoop. Then, for any
gap-filling scoops that are not executable, fill their
contents with f4s.

Do not remove iterator from file's data scoops

See merge request allzp/zipr!10

Thanks to a change to the time when scoops are
added to the file's data scoops, the clause that
removes empty data scoops should not *always*
remove empty scoops from the set of global scoops.

Resolve "Overlapping sections cause problem with padding code."

Closes #5

See merge request allzp/zipr!9

This fixes an issue where a pinned address was

1. unpinned
2. reserved as part of a chain
3. exists in a sled

and all hell broke loose. The fix is to make sure
that the pinned addresses are only recorded *after*
the initial unpinning code happens.

As a further fix, there should be a function that
unpins an address (it would reset the ibta of
the instruction and clear the pinned address map.)

Fix #5: Handle overlapping sections

Closes #5

See merge request allzp/zipr!8

Handle overlapping sections properly. This
was a problem with calculation of the gap
between two sections that happen to overlap.
It resulted in a negative gap that turned
into a very large positive number.

This will build zipr and check that it compiles.

Turn off warnings as errors for deprecated
features. Leaving these warnings as errors
breaks the build with newer versions of GCC.
