When building from same stream all nodes need to read
data from the same stream. In order to achive that there
is a new SyncMultiReader wrapper that sends the stream
concurrently to all readers. Readers must read at similar
speed or pauses will happen while they wait for each other.
Dockerfiles were already written to disk before sent. Now
the file written by first node is reused for others.

This is a preparation to shared local sources for bake
targets and makes it possible to have equality check
between locals from different targets.

When LocalDirs were changed to LocalMounts, this broke the
sharedKey computation that was based on the context directory
path. SharedKey defines if directory is valid candidate for
incremental context transfer and if not set properly then
different directories do metadata-based transfers to same destination.

This makes the code slightly more idiomatic, but the errors produced will
change slightly to prevent having to path NamedContext as argument.

This package is part of the classic builder, and was currently only used
for the IsURL utility, which is a very rudimentary check for a string having
a "https://" or "http://" scheme.
This patch copies the code as non-exported functions where they're used to
remove the dependency.

hasDigest would always be true when reaching this code, because the function
would return with an error when failing to resolve the digest;
if !hasDigest {
return nil, errors.Errorf("oci-layout reference %q could not be resolved", v.Path)
}

hasTag was always true as it was set to "true" when missing, in which case
the default (`:latest`) tag was applied;
localPath, tag, hasTag := strings.Cut(localPath, ":")
if !hasTag {
tag = "latest"
hasTag = true
}

This eases build driver migrations, as it allows aligning the default behavior.
