httpcaddyfile: Prevent rewrite routes from consolidating (fix #3108)
It's hard to say whether this was actually a bug, but the linked issue
shows why the old behavior was confusing. Basically, we infer that a
rewrite handler is supposed to act as an internal redirect, which likely
means it will no longer match the matcher(s) it did before the rewrite.

So if the rewrite directive shares a matcher with any adjacent route or
directive, it can be confusing/misleading if we consolidate the rewrite
into the same route as the next handler, which shouldn't (probably) match
after the rewrite is complete.

This is kiiiind of a hacky workaround to a quirky problem.

For edge cases like these, it is probably "cleaner" to just use handle
blocks instead, to group handlers under the same matcher, nginx-style.

b8cba62643 Refactor for CertMagic v0.10; prepare for PKI app
This is a breaking change primarily in two areas:
 - Storage paths for certificates have changed
 - Slight changes to JSON config parameters

Huge improvements in this commit, to be detailed more in
the release notes.

The upcoming PKI app will be powered by Smallstep libraries.

Expose TLS placeholders (#2982)
* caddytls: Add CipherSuiteName and ProtocolName functions

The cipher_suites.go file is derived from a commit to the Go master
branch that's slated for Go 1.14.  Once Go 1.14 is released, this file
can be removed.

* caddyhttp: Use commonLogEmptyValue in common_log replacer

* caddyhttp: Add TLS placeholders

* caddytls: update unsupportedProtocols

Don't export unsupportedProtocols and update its godoc to mention that
it's used for logging only.

* caddyhttp: simplify getRegTLSReplacement signature

getRegTLSReplacement should receive a string instead of a pointer.

* caddyhttp: Remove http.request.tls.client.cert replacer

The previous behavior of printing the raw certificate bytes was ported
from Caddy 1, but the usefulness of that approach is suspect.  Remove
the client cert replacer from v2 until a use case is presented.

* caddyhttp: Use tls.CipherSuiteName from Go 1.14

Remove ported version of CipherSuiteName in the process.

httpcaddyfile: tls: Load repeated cert files only once, with one tag
See end of issue #3004. Loading the same certificate file multiple times
with different tags will result in it being de-duplicated in the in-
memory cache, because of course they all have the same bytes. This
meant that any certs of the same filename loaded with different tags
would be overwritten by the next certificate of the same filename, and
any conn policies looking for the tags of the previous ones would never
find them, causing connections to fail.

So, now we remember cert filenames and their tags, instead of loading
them multiple times and overwriting previous ones.

A user crafting their own JSON might make this error too... maybe we
won't see it happen. But if it does, one possibility is, when loading
a duplicate cert, instead of discarding it completely, merge the tag
list into the one that's already stored in the cache, then discard.

caddyfile: tls: Ensure there is always a catch-all conn policy (#3005)
If user provides their own certs or makes any hostname-specific TLS
connection policy, it means that no TLS connection would be served for
any other hostnames, even though you'd expect that TLS is enabled for
them, too. So now we append a catch-all conn policy if none exist, which
allows all ClientHellos to be matched and served.

We also fix the consolidation of automation policies, which previously
gobbled up automation policies without hosts in favor of automation
policies with hosts. Instead of a host-specific policy eating up an
identical catch-all policy, the catch-all policy eats up the identical
host-specific policy, ensuring that the policy is applied to all hosts
which need it.

httpcaddyfile: Fix address parsing; don't infer port at parse-time
Before, listener ports could be wrong because ParseAddress doesn't know
about the user-configured HTTP/HTTPS ports, instead hard-coding port 80
or 443, which could be wrong if the user changed them to something else.
Now we defer port and scheme validation/inference to a later part of
building the output JSON.

httpcaddyfile: Move redir before rewrite
Using rewrite is like saying, "I accept this request, but I just need
to act on it as if it came in differently."

Whereas redir implies more of, "I reject this request, send it to me
differently, then I will process it."

Makes sense for it to come before rewrites. This can always be changed
using the 'order' global option if needed.

httpcaddyfile: Fix nested blocks; add handle directive; refactor
The fix that was initially put forth in #2971 was good, but only for
up to one layer of nesting. The real problem was that we forgot to
increment nesting when already inside a block if we saw another open
curly brace that opens another block (dispenser.go L157-158).

The new 'handle' directive allows HTTP Caddyfiles to be designed more
like nginx location blocks if the user prefers. Inside a handle block,
directives are still ordered just like they are outside of them, but
handler blocks at a given level of nesting are mutually exclusive.

This work benefitted from some refactoring and cleanup.

httpcaddyfile: Replace 'handler_order' option with 'order'
This allows individual directives to be ordered relative to others,
where order matters (for example HTTP handlers). Will primarily be
useful when developing new directives, so you don't have to modify the
Caddy source code. Can also be useful if you prefer that redir comes
before rewrite, for example. Note that these are global options. The
route directive can be used to give a specific order to a specific group
of HTTP handler directives.
