The alternative is to record enough information that the
trap handler know which registers contain cached globals
and can flush the registers back to their original locations.
That's significantly more work.

This only affects globals that have been written to.
Code that reads from a global should continue to registerize
as well as before.

Fixes #1304.

This broke a build on a Linux box I hadn't updated
in awhile. The hgignore files were preventing hg status
from showing and hg purge from cleaning up junk.

Embedded Go images in the installer dialog and
banner boxes, Go tree cloning uses version info
from the Go tool (readme updated), the installer
allows up/down-grading and reparing of the version
that's installed, added two registry values.

Added the (properly formatted) license file back,
the installer adds go\bin to the system PATH now,
the output package names are in line with the linux
and darwin versions, dist.bat extracts GOARCH in a
sane way, readme cleanup.

Tested on Windows 7 only. It would be helpful if
someone else could give it a try. See the readme
for details.

My theory is that the call to f() allocates, which triggers
a garbage collection, which itself may do some allocation,
which is being counted.  Running a garbage collection
before starting the test should avoid this problem.

Fixes #2894 (I hope).

* disallow embedding of C type (Fixes issue 2552)
* detect 0-length array (Fixes issue 2806)
* use typedefs when possible, to avoid attribute((unavailable)) (Fixes issue 2888)
* print Go types constructed from C types using original C types (Fixes issue 2612)

This fix changes _cgo_export.h to repeat the preamble from import "C".
Otherwise the fix to issue 2612 is impossible, since it cannot refer to
types that have not been defined.  If people are using //export and
putting non-header information in the preamble, they will need to
refactor their code.

morebuf holds a pc/sp from the last stack split or
reflect.call or panic/recover.  If the pc is a closure,
the reference will keep it from being collected.

moreargp holds a pointer to the arguments from the
last stack split or reflect.call or panic/recover.
Normally it is a stack pointer and thus not of interest,
but in the case of reflect.call it is an allocated argument
list and holds up the arguments to the call.

The garbage collector can avoid scanning this section, with
reduces collection time as well as the number of false positives.
