Andrei Vagin 5f4abad306 Fix a few typos 
It is an idea of running codespell as part of our presubmit checks.
Before enabling it for new changes, let's fix what it has found.

Shambhavi SrivastavaandgVisor bot c8e98d9f5e Add Points to some syscalls 
Added a raw syscall points to all syscalls. Added schematized syscall
points to the following syscalls:

  - timerfd_create
  - timerfd_settime
  - timerfd_gettime
  - fork, vfork
  - inotify_init, inotify_init1
  - inotify_add_watch
  - inotify_rm_watch
  - socketpair

Fabricio VoznikaandgVisor bot 2d6e64019b Faster proto serialization 
The use of protobuf.Any is convenient, but adds to proto serialization
time and number of memory allocations required to send a message.
Instead, we now use an enum to indentify the message and use it to
determine how to unmarshall the message on the receiveing end. It
also speeds up event consuption by not requiring a map from string
(proto names) to callbacks.

BenchmarkProtoAny-6   115.9 ns/op        210 B/op       4 allocs/op
BenchmarkProtoEnum-6   58.3 ns/op          2 B/op       1 allocs/op

Fabricio VoznikaandgVisor bot 8a24f200e9 Use proto structs for seccheck points 
Given that in most cases points are serialized to another process,
point data is now created diretly into protos.

As part of this change, infrastructure to track optional and context
fields was created to facilitate addition of lots of Points which is
needed for upcomming of changes.

Updates #4805

Currently the SST code is converting seccheck protos into SST protos
in the sentry before sending it to the API. After this change, SST
checker will be changed to send seccheck protos to the API and the
API then converts these into SST on the way to pubsub.
