libpmc: Explicitly whitelist json fields
Adds all missing Intel fields and turns jevents.c into an explicit white
list mechanism so that we no longer ignore important fields that often
invalidate the counter. The json event parser must now parse every
field on each architecture that we support. This has been tested by
running tinderbox and manually running jevent against our current json
repository. As a bonus I fixed spelling errors in the AMD JSON
definitions.

tests/kern/ssl_sendfile: fix 'random' and 'basic' flakyness
The read of c.sbytes needs to be synchronized with mutex. The problem was
fixed for 'truncate' and 'grow' with 8a9508563542, but these two suffer
from the same problem. Provide require_sbytes(), a locked wrapper around
ATF_REQUIRE() to reduce copy and paste.

ena: Verify that an ENA ring is in netmap only in native mode
netmap operates in two modes:
1) Emulated - netmap handling is done by the network stack, the
NIC driver operates transparently to netmap.
2) Native - netmap management is done by the NIC driver.
When checking whether a specific ENA ring is running in netmap
mode, only the following checks were done:
1. IFCAP_NETMAP - Check whether netmap capability is enabled on
the device.
2. NKR_NETMAP_ON - Check whether netmap is actively using this
ring.
The above checks implied that the netmap mode is native and the
ENA driver needs to handle the netmap logic.
The code was missing an explicit check on whether native mode
is actually on (NAF_NATIVE).
This led to a case where though emulated mode was used and
