Extract most of caddytls core code into external CertMagic package
All code relating to a caddytls.Config and setting it up from the
Caddyfile is still intact; only the certificate management-related
code was removed into a separate package.

I don't expect this to build in CI successfully; updating dependencies
and vendor is coming next.

I've also removed the ad-hoc, half-baked storage plugins that we need
to finish making first-class Caddy plugins (they were never documented
anyway). The new certmagic package has a much better storage interface,
and we can finally move toward making a new storage plugin type, but
it shouldn't be configurable in the Caddyfile, I think, since it doesn't
make sense for a Caddy instance to use more than one storage config...

We also have the option of eliminating DNS provider plugins and just
shipping all of lego's DNS providers by using a lego package (the
caddytls/setup.go file has a comment describing how) -- but it doubles
Caddy's binary size by 100% from about 19 MB to around 40 MB...!

tls: In HTTP->HTTPS redirects, preserve redir port in some circumstances
Only strip the port from the Location URL value if the port is NOT the
HTTPSPort (before, we compared against DefaultHTTPSPort instead of
HTTPSPort). The HTTPSPort can be changed, but is done so for port
forwarding, since in reality you can't 'change' the standard HTTPS port,
you can only forward it.

Apply Apache license to all .go source files (closes #1865)
I am not a lawyer, but according to the appendix of the license,
these boilerplate notices should be included with every source file.

httpserver: Flags to customize HTTP and HTTPS ports (incl. for ACME)
This commit removes _almost_ all instances of hard-coded ports 80 and
443 strings, and now allows the user to define what the HTTP and HTTPS
ports are by the -http-port and -https-ports flags.

(One instance of "80" is still hard-coded in tls.go because it cannot
import httpserver to get access to the HTTP port variable. I don't
suspect this will be a problem in practice, but one workaround would be
to define an exported variable in the caddytls package and let the
httpserver package set it as well as its own HTTPPort variable.)

The port numbers required by the ACME challenges HTTP-01 and TLS-SNI-01
are hard-coded into the spec as ports 80 and 443 for good reasons,
but the big question is whether they necessarily need to be the HTTP
and HTTPS ports. Although the answer is probably no, they chose those
ports for convenience and widest compatibility/deployability. So this
commit also assumes that the "HTTP port" is necessarily the same port
on which to serve the HTTP-01 challenge, and the "HTTPS port" is
necessarily the same one on which to serve the TLS-SNI-01 challenge. In
other words, changing the HTTP and HTTPS ports also changes the ports
the challenges will be served on.

If you change the HTTP and HTTPS ports, you are responsible for
configuring your system to forward ports 80 and 443 properly.

Closes #918 and closes #1293. Also related: #468.

Rewrote Caddy from the ground up; initial commit of 0.9 branch
These changes span work from the last ~4 months in an effort to make
Caddy more extensible, reduce the coupling between its components, and
lay a more robust foundation of code going forward into 1.0. A bunch of
new features have been added, too, with even higher future potential.

The most significant design change is an overall inversion of
dependencies. Instead of the caddy package knowing about the server
and the notion of middleware and config, the caddy package exposes an
interface that other components plug into. This does introduce more
indirection when reading the code, but every piece is very modular and
pluggable. Even the HTTP server is pluggable.

The caddy package has been moved to the top level, and main has been
pushed into a subfolder called caddy. The actual logic of the main
file has been pushed even further into caddy/caddymain/run.go so that
custom builds of Caddy can be 'go get'able.

The HTTPS logic was surgically separated into two parts to divide the
TLS-specific code and the HTTPS-specific code. The caddytls package can
now be used by any type of server that needs TLS, not just HTTP. I also
added the ability to customize nearly every aspect of TLS at the site
level rather than all sites sharing the same TLS configuration. Not all
of this flexibility is exposed in the Caddyfile yet, but it may be in
the future. Caddy can also generate self-signed certificates in memory
for the convenience of a developer working on localhost who wants HTTPS.
And Caddy now supports the DNS challenge, assuming at least one DNS
provider is plugged in.

Dozens, if not hundreds, of other minor changes swept through the code
base as I literally started from an empty main function, copying over
functions or files as needed, then adjusting them to fit in the new
design. Most tests have been restored and adapted to the new API,
but more work is needed there.

A lot of what was "impossible" before is now possible, or can be made
possible with minimal disruption of the code. For example, it's fairly
easy to make plugins hook into another part of the code via callbacks.
Plugins can do more than just be directives; we now have plugins that
customize how the Caddyfile is loaded (useful when you need to get your
configuration from a remote store).

Site addresses no longer need be just a host and port. They can have a
path, allowing you to scope a configuration to a specific path. There is
no inheretance, however; each site configuration is distinct.

Thanks to amazing work by Lucas Clemente, this commit adds experimental
QUIC support. Turn it on using the -quic flag; your browser may have
to be configured to enable it.

Almost everything is here, but you will notice that most of the middle-
ware are missing. After those are transferred over, we'll be ready for
beta tests.

I'm very excited to get this out. Thanks for everyone's help and
patience these last few months. I hope you like it!!
