History
Tate, Hongliang Tian c8a921fd4b Refactor program loader to handle many loadable segments 
The original implementation of program loader is written under the assumption
that there are only two loadable segments per ELF, one is code, and the other
is data. But this assumption is unnecessary and proves to be wrong for an ELF
on Alpine Linux, which has two extra read-only, loadable segments for security
hardening. This commit clears the obstacle towards running unmodified
executables from Alpine Linux.

In addition to getting rid of  the false assumption of two fixed loadable segments,
this commit improves the quality of the code related to program loading and
process initialization.
