3e31ee9455 legal: Additional permission under GNU GPL version 3 section 7
With the recent merging of embedded package imports and the entry CLI
package, it is now possible for users to build in mcl code into a single
binary. This additional permission makes it explicitly clear that this
is permitted to make it easier for those users. The condition is phrased
so that the terms can be "patched" by the original author if it's
necessary for the project. For example, if the name of the language
(mcl) changes, has a differently named new version, someone finds a
phrasing improvement or a legal loophole, or for some other
reasonable circumstance. Now go write some beautiful embedded tools!

dd0e67540f all: Remove deprecated io/ioutil package
Porting everything to the newer imports was trivial except for one
instance which required a very small refactor.

26bce5ddc0 engine: resources: Add a new http:proxy resource
This adds a new caching http proxy resource that can be autogrouped into
the core http:server resource, and which caches and serves files that it
received from a different http server. It first pulls them down when
they are initially requested, which makes it possible for us to use this
for provisioning a Linux installation without having to pre-rsync the
entire package repository.

7e1a4dea6c engine: resources: The http:file resource should allow directories
This expands the use of the http:file resource to allow it to be used as
a directory root.

67c72a0e86 engine: resources: Add an http:flag resource
This adds a new http:flag resource which can autogroup into an
http:server resource to receive actions from client HTTP requests, and
forward these values on to other resources.

377d62999f engine: resources: The kv resource can set un-mapped values
Previously the resource could only set values in a per-hostname
namespace, but for single, user-managed values, we'd like to be able to
control things entirely. Now this resource can do that.

b7d8a769db lang: funcs: core: Add value functions
This adds a new series of "get*" functions which can read values from
the associated "value" resources. The key name of the function must
match the name value of the resource for things to work.

Type unification isn't yet perfect in these scenarios, so you should use
casually and with caution.

2cbce963b7 engine: resources, lang: funcs, parser: Add panic magic
It's valuable to check your runtime values and to shut down the entire
engine in case something doesn't match. This patch adds some magic
plumbing to support a "panic" mechanism.

A new "panic" statement gets transparently converted into a panic
function and panic resource. The former errors if the input is not
empty. The latter must be present to consume the value, but doesn't
actually do anything.

d022d7f09e engine: resources: Rename the value field in value resource
Having a different name makes it more obvious, and also leaves us open

88b414b9a3 engine: resources: Add new value resource
This is a strange resource which is probably most useful for passing

only be used as a last resort and if you know exactly what you're doing.
