fxos: faster project loading through functions
...
- Compute analysis on-demand
- Faster function exploration, due to:
* Cache basic block's index in function
* Preallocate memory for 4 blocks per function
* Preallocate 32 instructions per superblock
* Assume functions do not cross vspace region boundaries
* Improve cutSuperblockAt() with lower-level code

* Update documentation about functions API

ending types, and calls that were misleading about the structure
* Fix the static analysis code not accounting for delay slots
* Improve/enrich the program diff structure

fxos: remove vspace as a session abstraction
...
And rewrite all existing commands to read from a binary instead.
The transition to the new data model is *not* complete because a bunch
of data is still hidden in the "Disassembly" inside the binary's virtual
space instead of being managed by the binary itself. Removing these is
the next step.

We look for constants in call instruction parameters, but this only
works for jsr because the register argument in [jmp @rn] is not known to
be a constant yet (some static analysis required).

Type e.g. "e 1 + 2 * 3". The first "+" throws a syntax error
(parentheses are needed around expressions) and the "*" another one
during the final exhaust_until_separator phase, which wasn't protected
by a try/catch.
