Cannot assume that g == m->curg at time of signal.
Must save actual g and restore.
Fixes flaky crashes with messages like
throw: malloc mlookup
throw: malloc/free - deadlock
throw: unwindstack on self
throw: free mlookup
(and probably others) when running cgo.

There's only one Go object file per package now,
so there's no need to parse the metadata and merge
metadata from multiple files. Just save the original
and use it as __.PKGDEF verbatim.

This avoids a crash when using cgo where glibc's malloc thinks
that it can use some of the memory following the symbol table.
This fails because the symbol table is mapped read-only, which
affects the whole page.

Although technically incorrect, we want this in order to parse X.509
certificates where a wildcard hostname ("*.example.com") has been put
into a PrintableString.
Fixes#850.

* Code for assignment, conversions now mirrors spec.
* Changed some snprint -> smprint.
* Renamed runtime functions to separate
interface conversions from type assertions:
convT2I, assertI2T, etc.
* Correct checking of \U sequences.
Fixes#840.
Fixes#830.
Fixes#778.

(caused certain files to not be idempotent under gofmt)
- corrected golden files for go/printer
- slightly simplified some code in nodes.go (no impact on formatting)
- these changes have no impact on gofmt output of .go files under src, misc
fallthrough statement considered harmful!

Specifically:
- introduced notion of "underlying type"
- removed notion of type compatibility
- consolidated rules about assignment compatibility in
assignment compatibility section
- be consistent with specyfing that nil is the value
for uninitialized variables that can be nil (this
was not specified clearly for pointers, functions, interfaces)
- added/fixed various related links throughout
- clarify language on conversions

Time (us) to draw a 200x200 src onto an image.RGBA dst with the Over
operator. Each case was measured three separate times, and the sorted
times are reported.
Fill case (where src is an image.ColorImage):
Before:
7438, 7511, 7526
After:
3073, 3087, 3102
Copy case (where src is an image.RGBA):
Before:
9506, 9510, 9563
After:
5262, 5300, 5344
