The 1.16 `io/fs` compatibility code was being built on 1.18 and 1.19.
Drop it completely as 1.16 is long EOL, and additionally drop 1.17 as it
has been EOL for a month and 1.18 is both the minimum Go supported by
the 20.10 branch, as well as a very easy jump from 1.17.

This utility was added in 442b45628e as part of
user-namespaces, and first used in 44e1023a93 to
set up the daemon root, and move the existing content;
44e1023a93/daemon/daemon_experimental.go (L68-L71)
A later iteration no longer _moved_ the existing root directory, and removed the
use of `directory.MoveToSubdir()` e8532023f2
It looks like there's no external consumers of this utility, so we should be
save to remove it.

(cherry picked from commit 4831ff9f27)
This fixes an inifinite loop in mkdirAs(), used by `MkdirAllAndChown`,
`MkdirAndChown`, and `MkdirAllAndChownNew`, as well as directories being
chown'd multiple times when relative paths are used.
The for loop in this function was incorrectly assuming that;
1. `filepath.Dir()` would always return the parent directory of any given path
2. traversing any given path to ultimately result in "/"
While this is correct for absolute and "cleaned" paths, both assumptions are
incorrect in some variations of "path";
1. for paths with a trailing path-separator ("some/path/"), or dot ("."),
`filepath.Dir()` considers the (implicit) "." to be a location _within_ the
directory, and returns "some/path" as ("parent") directory. This resulted
in the path itself to be included _twice_ in the list of paths to chown.
2. for relative paths ("./some-path", "../some-path"), "traversing" the path
would never end in "/", causing the for loop to run indefinitely:
```go
// walk back to "/" looking for directories which do not exist
// and add them to the paths array for chown after creation
dirPath := path
for {
dirPath = filepath.Dir(dirPath)
if dirPath == "/" {
break
}
if _, err := os.Stat(dirPath); err != nil && os.IsNotExist(err) {
paths = append(paths, dirPath)
}
}
```
A _partial_ mitigation for this would be to use `filepath.Clean()` before using
the path (while `filepath.Dir()` _does_ call `filepath.Clean()`, it only does so
_after_ some processing, so only cleans the result). Doing so would prevent the
double chown from happening, but would not prevent the "final" path to be "."
or ".." (in the relative path case), still causing an infinite loop, or
additional checks for "." / ".." to be needed.
| path | filepath.Dir(path) | filepath.Dir(filepath.Clean(path)) |
|----------------|--------------------|------------------------------------|
| some-path | . | . |
| ./some-path | . | . |
| ../some-path | .. | .. |
| some/path/ | some/path | some |
| ./some/path/ | some/path | some |
| ../some/path/ | ../some/path | ../some |
| some/path/. | some/path | some |
| ./some/path/. | some/path | some |
| ../some/path/. | ../some/path | ../some |
| /some/path/ | /some/path | /some |
| /some/path/. | /some/path | /some |
Instead, this patch adds a `filepath.Abs()` to the function, so make sure that
paths are both cleaned, and not resulting in an infinite loop.

The correct formatting for machine-readable comments is;
//<some alphanumeric identifier>:<options>[,<option>...][ // comment]
Which basically means:
- MUST NOT have a space before `<identifier>` (e.g. `nolint`)
- Identified MUST be alphanumeric
- MUST be followed by a colon
- MUST be followed by at least one `<option>`
- Optionally additional `<options>` (comma-separated)
- Optionally followed by a comment
Any other format will not be considered a machine-readable comment by `gofmt`,
and thus formatted as a regular comment. Note that this also means that a
`//nolint` (without anything after it) is considered invalid, same for `//#nosec`
(starts with a `#`).

pkg/urlutil (despite its poorly chosen name) is not really intended as a generic
utility to handle URLs, and should only be used by the builder to handle (remote)
build contexts.
- IsURL() only does a very rudimentary check for http(s):// prefixes, without any
other validation, but due to its name may give incorrect expectations.
- IsGitURL() is written specifically with docker build remote git contexts in
mind, and has handling for backward-compatibility, where strings that are
not URLs, but start with "github.com/" are accepted.
Because of the above, this patch:
- moves the package inside builder/remotecontext, close to where it's intended
to be used (ideally this would be part of build/remotecontext itself, but this
package imports many other dependencies, which would introduce those as extra
dependencies in the CLI).
- deprecates pkg/urlutil, but adds aliases as there are some external consumers.

brings in a large amount of new code, and most strings we generate will be ASCII,
so this would only be in case it's used for some user-provided string. We also
don't have a language to use, so would be using the "default".

Finish the refactor which was partially completed with commit
34536c498d, passing around IdentityMapping structs instead of pairs of
[]IDMap slices.
Existing code which uses []IDMap relies on zero-valued fields to be
valid, empty mappings. So in order to successfully finish the
refactoring without introducing bugs, their replacement therefore also
needs to have a useful zero value which represents an empty mapping.
Change IdentityMapping to be a pass-by-value type so that there are no
nil pointers to worry about.
The functionality provided by the deprecated NewIDMappingsFromMaps
function is required by unit tests to to construct arbitrary
IdentityMapping values. And the daemon will always need to access the
mappings to pass them to the Linux kernel. Accommodate these use cases
by exporting the struct fields instead. BuildKit currently depends on
the UIDs and GIDs methods so we cannot get rid of them yet.
