NetlinkRIB is currently allocating a page sized slice of bytes in a
for loop and it's also calling Getpagesize() in the same for loop.
This CL changes NetlinkRIB to preallocate the page sized slice of
bytes before reaching the for loop. This reduces memory allocations
and lowers the number of calls to Getpagesize() to 1 per NetlinkRIB
call.
This CL reduces the allocated memory from 141.5 MB down to 52 MB in
a test.

Update #1435
This proposal disables Setuid and Setgid on all linux platforms.
Issue 1435 has been open for a long time, and it is unlikely to be addressed soon so an argument was made by a commenter
https://code.google.com/p/go/issues/detail?id=1435#c45
That these functions should made to fail rather than succeed in their broken state.

These functions claimed to return error (an interface)
and be implemented entirely in assembly, but it's not
possible to create an interface from assembly
(at least not easily).
In reality the functions were written to return an errno uintptr
despite the Go prototype saying error.
When the errno was 0, they coincidentally filled out a nil error
by writing the 0 to the type word of the interface.
If the errno was ever non-zero, the functions would
create a non-nil error that would crash when trying to
call err.Error().
Luckily these functions (Seek, Time, Gettimeofday) pretty
much never fail, so it was all kind of working.

These are all real mistakes being corrected, but none

On DragonFly BSD, we adjust the ephemeral port range because
unlike other BSD systems its default ephemeral port range
doesn't conform to IANA recommendation as described in RFC 6355
and is pretty narrow.
On DragonFly BSD 3.6: default range [1024, 5000], high range [49152, 65535]
On FreeBSD 10: default range [10000, 65535], high range [49152, 65535]

Unfortunately FreeBSD 10 has changed its syscall arguments for
some reasons but as per request at golang-dev this CL does not
generate some structures, syscall numbers and constants as
compatible to FreeBSD 10 as follows:

Syscall number: Capsicum API is based on 9-STABLE
Constant: IFT_CARP, SIOCAIFADDR, SIOCSIFPHYADDR are based on 9-STABLE

CL 15750044 is not included as it involves more invasive changes to the linker which will need to be merged separately.

This CL adds a test that calls Mmap and Munmap through Syscall9
as the canary that detects assembly fragment breakage. For now
there is no package test that uses Syscall9 in the standard
library across all Unix-like systems.
Note that the package runtime owns its assembly fragments, so
this canary never works for runtime breakage.
