864c757a1c gc/runtime: pass type structure to makeslice. 
* inform garbage collector about memory with no pointers in it

1.9s	gcc reverse-complement.c

reverse-complement.go
4.5s / 3.5s	original, with/without bounds checks
3.5s / 3.3s	bounds check reduction
3.3s / 2.8s	smarter garbage collector
2.6s / 2.3s		assembler bytes.IndexByte
2.5s / 2.1s	even smarter garbage collector (this CL)

Makes the code look cleaner, even if it's a little harder to figure
out from the sort invariants.

d1740bb3a6 Remove global chanlock. 
On a microbenchmark that ping-pongs on lots of channels, this makes
the multithreaded case about 20% faster and the uniprocessor case
about 1% slower. (Due to cache effects, I expect.)

dc7355a974 Add flag -tabindent to gofmt: forces use of 
tabs for indentation even if -spaces is set.

Changes to gofmt:
- added -tabindent flag
- don't recompute parser and printer mode repeatedly

Changes to go/printer:
- provide new printing mode TabIndent

Changes to tabwriter:
- implement new mode TabIndent to use tabs independent
  of the actual padding character for leading empty columns
- distinguish between minimal cell width and tab width
  (tabwidth is only used if the output contains tabs,
  minwidth and padding are always considered)
- fixed and added more comments
- some additional factoring

By default, -tabindent is disabled and the default gofmt
behavior is unchanged. By setting -spaces and -tabindent,
gofmt will use tabs for indentation but do any other
alignment with spaces. This permits a user to change the
visible indentation by simply changing the editor's tab
width and the code will remain properly aligned without
the need to rerun gofmt.

bfbb31595b Map support for template.Execute(). 
Allows the developer to pass a map either by itself for
evaluation, or inside a struct. Access to data inside
maps is identical to the current system for structs, ie.

-Psuedocode-

mp map[string]string = {
	"header" : "A fantastic header!",
	"footer" : "A not-so-fantastic footer!",
}
template.Execute(mp)

...can be accessed using {header} and {footer} in
the template. Similarly, for maps inside structs:

type s struct {
	mp map[string]string,
}
s1 = new s
s1.mp["header"] = "A fantastic header!";
template.Execute(s1)

...is accessed using {mp.header}. Multi-maps, ie.
map[string](map[string]string) and maps of structs
containing more maps are unsupported, but then, I'm
not even sure if that's supported by the language.

Map elements can be of any type that can be written
by the formatters. Keys should really only be strings.

ef8f483c60 net: remove race condition on Close. 
Previously a netFd could be queued for reading/writing in the channel,
but close(2)'ed before pollServer got to it. In this case, the kernel
would consider the descriptor closed and the attempt to add it to the
epoll set would fail and panic.

This patch makes Close a roundtrip to the pollServer, although the
actual close(2) still occurs elsewhere to avoid blocking the
pollServer.

case. This empty string was being returned to the caller (of Client.Call
or Client.Go), resulting in a non-nil error response.

This change detects an empty-string Response.Error at the client, and
translates it into a nil value in Call.Error.

Tests updated to check error return in success cases.

bae4f5085e cmd/cc: Fix -I switch to handle a path with blankspaces correctly 
Currently, -I switch can't deal with a path containing spaces.
This commit simplify setinclude(), by removing the special case
of a string that had spaces. After this change, setinclude() will
merely add the given directories to the include path, if it does
not yet exist, and this approach works.

Will be needed for solving issue 115.

ad05d29103 crypto/rsa: handle the case of non-coprime blinds. 
We are dealing with the multiplicative group ℤ/pqℤ. Multiples of
either p or q are not members of the group since they cannot have an
inverse. (Such numbers are 0 in the subgroup ℤ/pℤ.)

With p and q of typical size (> 512 bits), the probability of a random
blind [1..pq-1] being a multiple of p or q is negligible. However, in
the unit tests, much smaller sizes are used and the event could occur.

This change checks the result of the ext GCD and deals with this case.

It also increases the size of p and q in the unit test as a large
number of the keys selected were p, q = 227,169.

2643f742a5 make.bash: detect and warn about SELinux policy that crashes us. 
The default SELinux policy on Fedora 12 (at least) disallows stack
pages to be +x. This causes all binaries written by 6g/6l to segfault
immedately. The 'true' way to fix this issue is to mark binaries with
the correct type. However, that assumes that 6l is going to detect
SELinux, figure out the correct type for the current distribution and
set the type (without libselinux).

For now we'll warn users and point them towards the way to enable
execstack for the whole system.
