New features:
* The syscall pass now resolves syscalls for the input target, provided
that an OS is mapped on the ROM region.
* Formalized the variations of print's arguments as a sequence (tree, to
be precise) of /promotions/.
* Added a short notion of Symbol and SymbolTable, and a loader for them.
Data files of type "symbol" are read as such and provide name to
syscalls or arbitrary addresses.
Code changes:
* The disassembly operation of the command-line interface is now finally
in its own file with more room.
* Encoded the tree structure of promotions as a sequence of (mainly
tail-calling) inter-calling methods in the print pass.
-> The cfg pass loads the function into memory, annotates leaders and
jumps, and resolves delay slots.
-> The pcrel pass currently computes locations for pc-relative moves and
jumps, but does not yet compute the pc-relative moved data.
-> The print pass displays the results of analysis with various layout
and formatting options.
