Since go-1.11beta1 archive/tar, tar headers with Typeflag == TypeRegA
(numeric 0) (which is the default unless explicitly initialized) are
modified to have Typeflag set to either tar.TypeReg (character value
'0', not numeric 0) or tar.TypeDir (character value '5') [1].
This results in different Typeflag value in the resulting header,
leading to a different Checksum, and causing the following test
case errors:
> 12:09:14 --- FAIL: TestTarSums (0.05s)
> 12:09:14 tarsum_test.go:393: expecting
> [tarsum+sha256:8bf12d7e67c51ee2e8306cba569398b1b9f419969521a12ffb9d8875e8836738],

> ... (etc.)
All the other code explicitly sets the Typeflag field, but this test
case is not, causing the incompatibility with Go 1.11. Therefore,
the fix is to set TypeReg explicitly, and change the expected checksums
in test cases).
Alternatively, we can vendor archive/tar again (for the 100th time),
but given that the issue is limited to the particular test case it
does not make sense.
This fixes the test for all Go versions.

Addresses https://github.com/moby/moby/pull/35089#issuecomment-367802698.
This change enables the daemon to automatically select an image under LCOW
that can be used if the API doesn't specify an explicit platform.
For example:
FROM supertest2014/nyan
ADD Dockerfile /
And docker build . will download the linux image (not a multi-manifest image)
And similarly docker pull ubuntu will match linux/amd64

This makes it a bit simpler to remove this interface for v2 plugins
and not break external projects (libnetwork and swarmkit).
Note that before we remove the `Client()` interface from `CompatPlugin`
libnetwork and swarmkit must be updated to explicitly check for the v1
client interface as is done int his PR.
This is just a minor tweak that I realized is needed after trying to
implement the needed changes on libnetwork.

Sometimes docker-master CI fails on rhel4+selinux configuration,
like this:
--- FAIL: TestMount (0.12s)
--- FAIL: TestMount/none-remount,size=128k (0.01s)
mounter_linux_test.go:209: unexpected mount option "seclabel" expected "rw,size=128k"
--- FAIL: TestMount/none-remount,ro,size=128k (0.01s)
mounter_linux_test.go:209: unexpected mount option "seclabel" expected "ro,size=128k"
Earlier, commit 8bebd42df2 (PR #34965) fixed this failure,
but not entirely (i.e. the test is now flaky). It looks like
either selinux detection code is not always working (it won't
work in d-in-d), or the kernel might or might not add 'seclabel'
option).
As the subject of this test case is definitely not selinux,
it can just ignore the option added by it.
While at it, fix error messages:
- add missing commas;
- fix a typo;
- allow for clear distinction between mount
and vfs (per-superblock) options.

Since Go 1.7, context is a standard package. Since Go 1.9, everything
that is provided by "x/net/context" is a couple of type aliases to
types in "context".
Many vendored packages still use x/net/context, so vendor entry remains
for now.

Now, every Unmount() call takes a burden to parse the whole nine yards
of /proc/self/mountinfo to figure out whether the given mount point is
mounted or not (and returns an error in case parsing fails somehow).
Instead, let's just call umount() and ignore EINVAL, which results
in the same behavior, but much better performance.
Note that EINVAL is returned from umount(2) not only in the case when
`target` is not mounted, but also for invalid flags. As the flags are
hardcoded here, it can't be the case.

The mountinfo parser implemented via `fmt.Sscanf()` is slower than the one
using `strings.Split()` and `strconv.Atoi()`. This rewrite helps to speed it
up to a factor of 8x, here is a result from go bench:
> BenchmarkParsingScanf-4 300 22294112 ns/op
> BenchmarkParsingSplit-4 3000 2780703 ns/op
I tried other approaches, such as using `fmt.Sscanf()` for the first
three (integer) fields and `strings.Split()` for the rest, but it slows
things down considerably:
> BenchmarkParsingMixed-4 1000 8827058 ns/op
Note the old code uses `fmt.Sscanf`, when a linear search for '-' field,
when a split for the last 3 fields. The new code relies on a single
split.
I have also added more comments to aid in future development.
Finally, the test data is fixed to now have white space before the first field.

The flow of getSourceMount was:
1 get all entries from /proc/self/mountinfo
2 do a linear search for the `source` directory
3 if found, return its data
4 get the parent directory of `source`, goto 2
The repeated linear search through the whole mountinfo (which can have
thousands of records) is inefficient. Instead, let's just
1 collect all the relevant records (only those mount points
that can be a parent of `source`)
2 find the record with the longest mountpath, return its data
This was tested manually with something like
```go
func TestGetSourceMount(t *testing.T) {
mnt, flags, err := getSourceMount("/sys/devices/msr/")
assert.NoError(t, err)
t.Logf("mnt: %v, flags: %v", mnt, flags)
}
```
...but it relies on having a specific mount points on the system
being used for testing.

Functions `GetMounts()` and `parseMountTable()` return all the entries
as read and parsed from /proc/self/mountinfo. In many cases the caller
is only interested only one or a few entries, not all of them.
One good example is `Mounted()` function, which looks for a specific
entry only. Another example is `RecursiveUnmount()` which is only
interested in mount under a specific path.
This commit adds `filter` argument to `GetMounts()` to implement
two things:
1. filter out entries a caller is not interested in
2. stop processing if a caller is found what it wanted
`nil` can be passed to get a backward-compatible behavior, i.e. return
all the entries.
A few filters are implemented:
- `PrefixFilter`: filters out all entries not under `prefix`
- `SingleEntryFilter`: looks for a specific entry
Finally, `Mounted()` is modified to use `SingleEntryFilter()`, and
`RecursiveUnmount()` is using `PrefixFilter()`.
Unit tests are added to check filters are working.
[v2: ditch NoFilter, use nil]
[v3: ditch GetMountsFiltered()]
