Preloading libmozsandbox allows the symbol interpositions used by
sandboxing to be defined there instead of statically linked into the
executable; this patch also does that.

rename : security/sandbox/linux/interpose/SandboxHooks.cpp => security/sandbox/linux/SandboxHooks.cpp
Now that SandboxInfo is always part of libmozsandbox, instead of being
in different places depending on widget, it doesn't need to be a
separate directory anymore.
Also updates a few comments that referenced it.

rename : security/sandbox/linux/common/LinuxSched.h => security/sandbox/linux/LinuxSched.h
rename : security/sandbox/linux/common/SandboxInfo.cpp => security/sandbox/linux/SandboxInfo.cpp
rename : security/sandbox/linux/common/SandboxInfo.h => security/sandbox/linux/SandboxInfo.h
This way they'll continue to be at the beginning of the symbol search
path after mozsandbox returns to being a shared library instead of
statically linked into plugin-container.

Making readlink() always fail with EINVAL (the result of applying it
to a non-symlink) worked on B2G, but this is not the case on desktop.
(Note: originally the idea for the B2G file broker was that it would
ignore symlinks and map lstat to stat, so that behavior for readlink
would have been consistent, but as eventually implemented it does do
lstat as actual lstat.)
In particular, this seems to be causing something in the graphics
library stack to change what GL renderer it uses (?), and on some
systems the presence of the readlink->EINVAL rule causes it to load a
version of the llvmpipe software renderer with a crash bug, instead of
(we assume) some other driver that works.
jprof is an in-tree profiling tool that runs on Linux.
This fixes the error:
Sandbox: seccomp sandbox violation: pid 29698, syscall 38, args 0 140731305513136 0 830 22509600 1. Killing process.
Sandbox: crash reporter is disabled (or failed); trying stack trace:
Sandbox: frame #01: __GI_setitimer (/build/glibc-GKVZIf/glibc-2.23/time/../sysdeps/unix/syscall-template.S:84)
Sandbox: frame #02: startSignalCounter(unsigned long) (.../mozilla-central/mozilla/tools/jprof/stub/libmalloc.cpp:464)
which occurs during shutdown when running with jprof enabled via the
JPROF_FLAGS environment variable containing JP_DEFER without actually
sending the signal to start jprof. It presumably occurs sooner if jprof
is actually used either via JP_START or by senging a SIGPROF/SIGALRM.
With the patch, these steps run to completion.

Adds content sandbox metadata to parent and child crash reports:
Includes the value of pref security.sandbox.content.level,
whether or not the system is capable of sandboxing, if the
sandbox was successfully turned on, and (on Linux systems)
the sandbox capabilities flags.
New crash report keys:
"ContentSandboxLevel" in parent and content
"ContentSandboxCapable" in parent
"ContentSandboxEnabled" in content
"ContentSandboxCapabilities" in content on Linux
Callers should use a UniquePtr to hold the platform handle.

This removes the unnecessary setting of c-basic-offset from all
python-mode files.
This was automatically generated using
perl -pi -e 's/; *c-basic-offset: *[0-9]+//'
... on the affected files.
The bulk of these files are moz.build files but there a few others as
well.

fork() will now fail with EPERM instead of crashing; see code comment
and bug for more info. Tested with GTK3 Oxygen theme and SCIM, which
both seem to work. Also verified that GMP child processes still crash
on fork().
