Using a value such as `--cpuset-mems=1-9223372036854775807` would cause
`dockerd` to run out of memory allocating a map of the values in the
validation code. Set limits to the normal limit of the number of CPUs,
and improve the error handling.

Files that are suffixed with `_linux.go` or `_windows.go` are
already only built on Linux / Windows, so these build-tags
were redundant.

Update golang.org/x/sys to 95c6576299259db960f6c5b9b69ea52422860fce in
order to get the unix.Utsname with byte array instead of int8/uint8
members.
This allows to use simple byte slice to string conversions instead of
using charsToString or its open-coded version.
Also see golang/go#20753 for details.

This function was only being used from a single place opts/opts.go. This
change moves it from a incohesive package (parsers) to the single place it
is used.
Also made a bunch of the helper methods private because they are not used
by any external modules.

These filters are only use to interchange data between clients and daemons.
They don't belong to the parsers package.

Improves the current filtering implementation complixity.
Currently, the best case is O(N) and worst case O(N^2) for key-value filtering.
In the new implementation, the best case is O(1) and worst case O(N), again for key-value filtering.

Before this patch libcontainer badly errored out with `invalid
argument` or `numerical result out of range` while trying to write
to cpuset.cpus or cpuset.mems with an invalid value provided.
This patch adds validation to --cpuset-cpus and --cpuset-mems flag along with
validation based on system's available cpus/mems before starting a container.
