222deeec36 proc,debugger: implement logical breakpoints (#1717)
Modifies FindFileLocation, FindFunctionLocation and LineToPC as well as
service/debugger to support inlining and introduces the concept of
logical breakpoints.

For inlined functions FindFileLocation, FindFunctionLocation and
LineToPC will now return one PC address for each inlining and one PC
for the concrete implementation of the function (if present).

A proc.Breakpoint will continue to represent a physical breakpoint, at
a single memory location.

Breakpoints returned by service/debugger, however, will represent
logical breakpoints and may be associated with multiple memory
locations and, therefore, multiple proc.Breakpoints.

The necessary logic is introduced in service/debugger so that a change
to a logical breakpoint will be mirrored to all its physical
breakpoints and physical breakpoints are aggregated into a single
logical breakpoint when returned.

6b20e880e2 *: add option to re-record recorded targets (#1702)
Adds a '-r' option to the 'restart' command (and to the Restart API)
that re-records the target when using rr.

Also moves the code to delete the trace directory inside the gdbserial
package.

7afda8dbe0 proc,service: remove support for locspec '<fnname>:0' (#1588)
The location specified '<fnname>:0' could be used to set a breakpoint
on the entry point of the function (as opposed to locspec '<fnname>'
which sets it after the prologue).
Setting a breakpoint on an entry point is almost never useful, the way
this feature was implemented could cause it to be used accidentally and
there are other ways to accomplish the same task (by setting a
breakpoint on the PC address directly).

48f1f51ef9 Miscellaneous logging improvements (#1525)
* *: use loglevel to control what gets logged instead of output redirection

This stops logrus from doing all the formatting just to discard it
immediately afterwards.

* logflags: replace default formatter of logrus

The default formatter of logrus emits logs in two different formats
depending on whether or not the output is going to a terminal. The
output format for non-terminals is indented to be machine readable, but
we mostly read logs ourselves and the excessive quoting makes that
format unreadable.
When outputting to terminals it uses ANSI escape codes unconditionally,
without checking whether the terminal it is connected to actually
supports colors.

This commit replaces the default formatter with a much simpler
formatter that always uses a more readable format, doesn't use colors
and places the key-value pairs at the beginning of the line (which is a
better match for how we use them).

* cmd/dlv: add command line options to redirect logs

Adds two options, --log-to-file and --log-to-fd, to redirect logs to a
file or to a file descriptor.

When one of those two options is specified the "API server listening
at:" message will also be redirected to the specified file/file
descriptor.
This allows clients that want to use the "API server listening at:"
message to do so even if they want to redirect the target's stdout to
another file or device.

Implements #1179, #1523

4c9a72e486 *: Update import name to github.com/go-delve/delve
The repository is being switched from the personal account
github.com/derekparker/delve to the organization account
github.com/go-delve/delve. This patch updates imports and docs, while
preserving things which should not be changed such as my name in the
CHANGELOG and in TODO comments.

b5cf584564 proc/gdbserial: backward continue should stop at start of process
ContinueOnce didn't detect the way RR signals that it has reached the
start of the process and would never finish.

d85cb61cad tests: call RunTestsWithFixtures everywhere we use BuildFixture
If we don't build artifacts aren't removed after the tests run. Also
add a check to prevent this mistake from reoccuring.

e47599d09a proc: remove proc.Process.Halt
The proper way to stop a running process is to call RequestManualStop,
which most code already did with the exception of some old test code.
