59c5d848e5 linux: Refactor ptrace usage.
1) Add PtraceConnection which serves as the base class for specific
types of connections Crashpad uses to trace processes.
2) Add DirectPtraceConnection which is used when the handler process
has `ptrace` capabilities for the target process.
3) Move `ptrace` logic into Ptracer. This class isolates `ptrace` call
logic for use by various PtraceConnection implementations.

6b5f139d88 linux: Add ProcessReader
ProcessReader is responsible for collecting information needed to build
a snapshot of the target process, independent of the Snapshot
interface. This CL includes implementation and tests for collecting
thread information, but does not yet collect module information.
