a0115e3a15 bugfix: Issue #170 (partial) set function breakpoints on the first instruction 
the entry point of a function is the beginning of the prologue, which can be run multiple times for each invocation of a function if the stack needs to be expanded or the scheduler needs to be run.

3cee10d8bc Implement 'trace' subcommand 
Allows a user to execute `dlv trace [regexp]` and Delve will execute the
program and output information on functions matching [regexp].

1ce255ffa3 Remove any printing from core proc package 
Also, reorganizes some code.

Initially, the `proc` package emitted a lot of output. Now, that should
not be the case. The `proc` package should never print, for any reason.
That should be handled by clients.

aa71d787aa Always stop the world after trapWait in resume 
We do not need to verify a current breakpoint, nor do a redundant check
on whether we have been asked to manually halt. Assume trapWait has done
its due diligence and stop the world once it returns.

4d1dc5ad0e Inject SIGTRAP for manual stop 
Instead of fighting against the normal flow, just signal a SIGTRAP and
let the existing flow handle it, as long as we set the halt flag
correctly the system should halt.

2fcbc4bdef ClearBreakpoint should clear a hardware breakpoint from all threads 
additionally fixes a bug when Detach is called on an exiting/exited thread: dbp.CurrentThread could point to a thread that has already been removed from dbp.Threads by trapWait which will lead to a nil pointer dereference caused proc.Process.clearBreakpoint getting nil from dbp.Threads[tid]
