change option syntax; less exceptions; better autocompletion 
* Change option syntax to <name>=<value>, with mandatory "=". This is
  still not great, but manageable.
* Remove the Session::require_vspace() function, whose named overload
  was misused (to check for the existence of a named space), and the
  associated exceptions. Explicit error flow is better error flow.
* Change the autocompletion system to generate all options in a vector
  of strings and then iterate, rather than using generators.
* Add completion for symbols.

masive improvements to memory use by compacting core objects 
* Store CpuRegister on a single byte
* Store operation sizes (0, 1, 2, 4) on a single byte
* Share the (disp) and (imm) fields of instruction arguments
* Store instructions as char[12] instead of std::string (>32B)
* Store instruction args in Argument[2], not std::vector (>24B)

Size changes:
  CpuRegister:    4B ->  1B
  Argument:      24B ->  8B
  Instruction:  >64B -> 32B

This reduced the malloc size from 3.3M to 177k after a standard 40-line
disassembly (this excludes OS files mapped to memory), and improved the
loading time for the SH3 instruction table by about 30% (100 ms -> 65
ms).
