terminal: m caps

[nick1udwig]

Problem

m doesn't send caps with messages, #579 #581

Solution

Attach caps that were issued by a given process and that are held by terminal to m Requests.

Testing

m our@contacts:contacts:sys "GetNames"

Docs Update

None

Notes

This still doesn't resolve #579 & #581 completely. The issue that remains is that there is no way for a process to pass a userspace cap to terminal. We either need to:

1. Change manifest field grant_capabilities to allow non-messaging caps to be granted,
2. Add a terminal:terminal:sys api that allows processes to give it capabilities.

Change manifest field grant_capabilities to allow non-messaging caps to be granted

it's an oversight that this doesn't currently work -- i'm surprised this code does not allow it:
