This is needed to avoid circular dependencies between the vfs and kernel
packages.

Michael Pratt 76483b8b1e Check sigsetsize in rt_sigaction
This isn't in the libc wrapper, but it is in the syscall itself.

Discovered by @xiaobo55x in #1625.

Adin Scannell 0e2f1b7abd Update package locations.
Because the abi will depend on the core types for marshalling (usermem,
context, safemem, safecopy), these need to be flattened from the sentry
directory. These packages contain no sentry-specific details.

Adin Scannell c98e7f0d19 Signalfd support
Note that the exact semantics for these signalfds are slightly different from
Linux. These signalfds are bound to the process at creation time. Reads, polls,
etc. are all associated with signals directed at that task. In Linux, all
signalfd operations are associated with current, regardless of where the
signalfd originated.

In practice, this should not be an issue given how signalfds are used. In order
to fix this however, we will need to plumb the context through all the event
APIs. This gets complicated really quickly, because the waiter APIs are all
netstack-specific, and not generally exposed to the context.  Probably not
worthwhile fixing immediately.

Adin Scannell 6728f09910 Fix sigaltstack semantics.
Walking off the bottom of the sigaltstack, for example with recursive faults,
results in forced signal delivery, not resetting the stack or pushing signal
stack to whatever happens to lie below the signal stack.
