This will remove the use of current time for syslog.time and introduce
a new column called 'datetime'.
Events now uses an "optimize_id" alongside "optimize" to prevent returning
colliding events added within the same second as the previous genTable call.
Along with the platform defines and platform string defines provided by
CMake to the build, add a PLATFORM_MASK define.
Use this define as a platform-type mask with the PlatformType enum.
This includes a minor SDK refactor as it move quite a few specialized
functions and facilities from core.h into system.h. There was a breaking point
for needing to frequently update core includes.
The new logger systemLog function allows a call site to bypass logging config
and write a line to the OS logger (aka syslog).
2. Introduce a SQLite-based database plugin
3. Refactor database usage to include local 'fast-calls'
4. Introduce an 'ephemeral' database plugin for testing (like a mock)
The refactor of config/packs was initiated because event subscribers needed
a method for toggling `::init` based on some configurable option. In the case
of auditd, turning on the support with `--disable_audit=false` used to start
auditing the EXECVE syscall. It was understandable that this would cause
latency based on the number of processes executing per measure of time.
A new `socket_events` table will do the same but for `bind` and `connect`. These
are less-obvious and for now, require a scan of /proc for socket tuples. In the
future this file descriptor to socket tuple will be faster.
Previously, event publishers used a canonicalized 'type' name for async callbacks.
This type was used to lookup the publisher plugin in the registry as well as for backing store namespacing.
The type is still used but subscribers, which made heavy used of the lookup, store the value locally.
This prevents unneeded publisher plugin allocation when adding events.
