1c0c252880 6l, 8l: include ELF header in PT_LOAD mapping for text segment
Due to page boundary rounding, the header would have
been loaded as part of the text segment already, but this
change placates the "paxctl" tool on so-called hardened
Linux distributions (as if normal distributions weren't already
hard enough to use).

47c4416b7e godashboard: bz2 compress logs in data store
This results in a 10-20x size reduction per record.
(from ~150kb to ~10kb)

This revision has been pushed live, as I'm in the process of
converting Log records to bz2-compresed CompressedLog records.
I would have waited but we're running seriously low on space
and it seemed like a sane (and reversible) move.

3ffbd57b94 syscall: match linux Setsid function signature to darwin
SETSID does return an errno - any reason why it has been done this
way in zsyscall_linux_* ? Otherwise it should be the same as darwin.

From SETSID(2) on my Linux box:

ERRORS
       On error, -1 is returned, and errno is set.

Fixes #730

3cfa2c3ddf json: scanner, Compact, Indent, and tests
This is the first of probably four separate CLs
for the new implementation of the json package.

The scanner is the core of the new implementation.
The other CLs would be the new decoder,
the new encoder, and support for JSON streams.

0b2e0265ae the android runner script
this is a version synthesized from rsc's, dean's and my
	versions. changes and updates:

	- embeds the retval script and pushes a new version to the
          device if needed
	- passes arguments correctly to the program on the device
	- export GOARCH, GOTRACEBACK and GOGC from the local
          environment to the device.
	- added times.out support to run-arm

	enabled a few tests that are now passing and moved the
	GOGC=off workaround to run-arm.

The command "godoc -src pkg_name" should output the interface of the named package, but it excludes all duplicate entries. Also the command "godoc -src pkg_name method_name" will output the source code only for one method even if there are more of them with the same name in the same package. This patch set fixes this issue.

1ab15fac22 fmt format verb %b bug
fmt.Printf("%b", int8(-1)) prints 64 ones instead of 8.
This happens only for signed integers (int8, in16 and int32). I guess it's because of the way the conversion between integer types works. From go spec: "Conversions between integer types. If the value is a signed quantity, it is sign extended to implicit infinite precision ....". And there are several conversions to int64 and uint64 in the fmt package. This pathch solves only half of the problem. On a 32 bit system, an fmt.Printf("%b", int(-1)) should still print 64 ones.
