Four changes:
- implement +validate-u to allow %u requests over the network
- make +validate-x use our local marks to make %x requests generally
work over the network
- in +start-request, if a foreign ship is making a request that we
shouldn't send over the network, ignore it. This closes a DOS vector.
- in +duce, if we're about to make a request to a foreign ship which
they won't be able to answer, crash the event.
Combined, these fix many of the common cases of weirdness around foreign
clay requests. Notably absent is a fix for reading `%a` across the
network, which I still maintain should happen against the foreign
hoon/zuse.

By factoring their shared logic out into +build-dependency, which gets
passed the relevant details about how to track the file being built in
the dependency stack.
Hoon files may want to import nouns from all files in a given directory.
/~ lets you do so, importing as a (map @ta *) (but with typed values).
Note the description as "directories" here, instead of "path prefix".
The behavior, as implemented, will not include /path/hoon for /~ /path,
instead only including /path/more/hoon and more deeply nested files.
This seems to be, generally, the behavior you want, for example when
importing from /app/myapp/* for /app/myapp/hoon.
Actually using the resulting map requires some manual casting, which is
not ideal. Some code style improvement work remains to be done as well.
In +en-json, the vast majority of our time is in +jesc (json string
escaping). Since ships will always be string-safe, we pretend they're
numbers to bypass the escaper. This saves about a second on initial
landscape load.
Avoid allocating hundreds of thousands of cells when giving large
requests. This took the footprint of this function on initial landscape
load from 1 second to 100 ms.
We commonly print many names in a row, often the same ones. For
example, on landscape's initial load, we send all the members of all the
groups we're in, and there's substantial overlap.
At least half the cost is in +fein, which is not currently jetted, but I
believe there's an old jet in the git history.
