d108fd04a5 linux: Add PtraceConnection::ReadFileContents 
Some files, such as /proc/[pid]/maps, may not be accessible to the
handler. This enables the handler access to the contents of those files
via the broker.

This change reads maps and auxv using ReadFileContents.

0924e56751 linux: Add PtraceBroker and PtraceClient 
A PtraceBroker/Client pair implement a PtraceConnection over a socket.
The broker runs in a process with `ptrace` capabilities for the target
process and serves requests for the client over a socket.
