[PATCH v3 0/2] Implement pahole-like 'ptype /o' option (and do some code reorg)

[Sergio Durigan Junior]

Changes from v2:

- Split the patch between #1 (code reorganization) and #2 (actual
  implementation of 'ptype /o').

- Add a few more tests; fix a few thinkos in the testcase.

- Remove leftover code.


Hi,

This is the third version of the patch, which is now a series.
Functionality hasn't changed; this is mostly a reorganization of the
patch into two patches (one for code movement, another for the actual
implementation of 'ptype /o').  Each patch contains an explanation of
what it does.

The docs have already been approved by Eli.
