ca9765d83a Make the reflection library match the reflection string which 
6g generates for functions: expect the keyword "func".  The
older reflection syntax, without the "func", is still
recognized for simplicity in parsing interface reflection
strings.

b87e3e8b7f * move go-specific loader code 
into gc directory, where it gets included as ../gc/ldbody
this is similar to the assemblers including ../cc/lexbody
and ../cc/macbody.

* hook go-specific loader code into 8l.

* make current 8.out.h and 6.out.h backward compatible
with plan 9's versions.  i had added some constants in
the middle of enums and have now moved them to the end.
this keeps us from invalidating old .8 and .6 files.
not sure how much it really matters, but easy to do.

4e84174816 Separate the alignment of a field from the alignment of the 
type of the field.  Use the field alignment to compute the
size of a structure.

This may help 8g but is mainly for gccgo.  gccgo maintains the
standard C/C++ ABI for structure field alignment.  For the
i386, this requires that a float64 field in a struct be
aligned on a 32-bit boundary, although for efficiency a
variable of type float64 or []float64 should be aligned on a
64-bit boundary.

I also removed the unused size field from structField.

99cc2fee81 This is really two changes in one but given interdependencies 
and expected review latency I needed to combine the CLs.

1. Made the 5* toolpath build using the go build
   system. Hooked the subdirectories to clean.bash but added a
   separate make5.bash for now. Minor massage to make the code
   more similar to the current structure of 6c/6a/6l.

2. Change all references from long to int32 in line with
   similar change for the other toolchains.

The end result is that 5c, 5a and 5l can now be compiled and
the executables start up properly. Haven't thrown any input at
them yet.

1e37e8a417 document Conn interface better, in preparation 
for per-method interface documentation
by mkdoc.pl.

implement timeouts on network reads
and use them in dns client.

also added locks on i/o to ensure writes
are not interlaced.

af678a593d new approach for generating sysimport.c 
(renamed to avoid any conflict with old p4 copies).

this approach doesn't require auto-generating
files also kept in p4, so it should be easier on
go users who don't sync very often.

this approach will be more work for go developers:
builtin.c needs to be copied to builtin.c.boot in p4
as new functions are added.  mkbuiltin does this
for certain $USERs to help us remember.
