We don't need this micro-optimization which just obfuscates the sources
for negligible performance gains. (Un)likeliness of branches in almost
all cases should be derived from profiling, not from hand-written hints,
using profile-guided optimization.
Before argv[0] was treated specially and was changed to a value
from manifest file. Now this happens only if binary was run as
a manifest i.e. `./pal_loader path_to_manifest_file`.
Plenty of bugfixes for Linux kernel later than 3.5 and Ubuntu later than 10.10.
More organized code to improve portability.
Regression tests for Pal to test completeness of implementation.
