[Object] Refactor build ID parsing into Object lib.

This makes parsing for build IDs in the markup filter slightly more
permissive, in line with fromHex.

It also removes the distinction between missing build ID and empty build
ID; empty build IDs aren't a useful concept, since their purpose is to
uniquely identify a binary. This removes a layer of indirection wherever
build IDs are obtained.

[Symbolizer] Implement contextual symbolizer markup elements.

This change implements the contextual symbolizer markup elements: reset,
module, and mmap. These provide information about the runtime context of
the binary necessary to resolve addresses to symbolic values.

Summary information is printed to the output about this context.
Multiple mmap elements for the same module line are coalesced together.
The standard requires that such elements occur on their own lines to
allow for this; accordingly, anything after a contextual element on a
line is silently discarded.

Implementing this cleanly requires that the filter drive the parser;
this allows skipped sections to avoid being parsed. This also makes the
filter quite a bit easier to use, at the cost of some unused
flexibility.
