It was not really "inserting" anything, just formatting and appending.
Simplify this by changing this in to a `getUpstreamUserAgent()` function
which returns the upstream User-Agent (if any) into a `UpstreamClient()`.

Use a const for the characters to escape, instead of implementing
this as a generic escaping function.

The User-Agent includes the kernel version, which involves making a syscall
(and parsing the results) on Linux, and reading (plus parsing) the registry
on Windows. These operations are relatively costly, and we should not perform
those on every request that uses the User-Agent.
This patch adds a sync.Once so that we only perform these actions once for
the lifetime of the daemon's process.

Older versions of Go don't format comments, so committing this as
a separate commit, so that we can already make these changes before
we upgrade to Go 1.19.

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.

This adds support for the passthrough on build, push, login, and search.
Revamp the integration test to cover these cases and make it more
robust.
Use backticks instead of quoted strings for backslash-heavy string
contstands.

Changes how the Engine interacts with Registry servers on image pull.
Previously, Engine sent a User-Agent string to the Registry server
that included only the Engine's version information. This commit
appends to that string the fields from the User-Agent sent by the
client (e.g., Compose) of the Engine. This allows Registry server
operators to understand what tools are actually generating pulls on
their registries.
