This already happens in the getCertificate function, but doing it here
guarantees case insensitivity across the board for this handshake.

We renamed caddytls.ErrStorageNotFound to caddytls.ErrNotExist to more
closely mirror the os package. We changed it to an interface wrapper
so that the custom error message can be preserved. Returning only "data
not found" was useless in debugging because we couldn't know the
concrete value of the error (like what it was trying to load).

Users can do a type assertion to determine if the error value is a "not
found" error instead of doing an equality check.

A Caddyfile using *.example.com as its site address would be subject to
this bug at renewal time, as it would use the literal "*.example.com"
value instead of the name being passed in to obtain a certificate.
This change fixes the LoadSite call so that it looks in the proper
directory for the certificate resources.

Caddyfiles read from STDIN now have server types associated with them.

Most of these were fixed by handling errors that were previously
unhandled (oops).

* Support for lego's timeout option

* Changed IntVar to DurationVar for catimeout

* Modified catimeout according to mholt's comments

Use naoina/toml for MIT license. Make proxy_test work in any directory.

Some tests were running into this issue:

Putting the sockets into temp dirs fixes the problem.

Add 'status' middleware instead of 'status' directive for 'rewrite' middleware

Actually set tls.Config.PreferServerCipherSuites

It was set by default on the caddy-internal config object, and even
checked for conflicts, but it was never actually reflected on the
tls.Config.

This will have user-visible changes: a client that prefers, say, AES-CBC
but also supports AES-GCM would have used AES-CBC befor this, and will
use AES-GCM after.

This is desirable and important behavior, because if for example the
server wanted to support 3DES, but *only if it was strictly necessary*,
it would have had no way of doing so with PreferServerCipherSuites
false, as the client preference would have won.

This change is still experimental.

This function should not be used outside of development. It destroys the
absolute ordering and guarantees of correctness. Multiple uses of it
may work fine, but maybe not if they overlap, causing non-deterministic
builds which is bad. However, this can be convenient when developing
a plugin by calling it from an init() function, since you don't have
to modify the Caddy source code just to try your plugin.

Keep quic protocol headers only between one hop

Removing quic protocol headers from being persisted during proxy requests.
Not removing them could lead to the client attempting to connect to the wrong port.
This makes the quic headers consistent with other protocol headers.

Add plugin capabilities for tls storage.

To use a plugged in storage, specify "storage storage_name" in the tls block of the Caddyfile, by default, file storage will be used

No need to check if SiteExists if the config is not managed or the name
does not even qualify.

Proxy: Set MaxIdleConnsPerHost to -1 to prevent Idle Conns

Proxy: Instead of setting DisableKeepAlives, set MaxIdleConnsPerHost to -1 to prevent net/http from pooling the connections. DisableKeepAlives causes net/http to send a Connection: Closed header which is bad. Fixes #1056
