* proc/core: off-by-one error reading ELF core files
core.(*splicedMemory).ReadMemory checked the entry interval
erroneously when dealing with contiguous entries.
* terminal,service,proc/*: adds dump command (gcore equivalent)
Adds the `dump` command that creates a core file from the target process.
Backends will need to implement a new, optional, method `MemoryMap` that
returns a list of mapped memory regions.
Additionally the method `DumpProcessNotes` can be implemented to write out
to the core file notes describing the target process and its threads. If
DumpProcessNotes is not implemented `proc.Dump` will write a description of
the process and its threads in a OS/arch-independent format (that only Delve
understands).
Currently only linux/amd64 implements `DumpProcessNotes`.
Core files are only written in ELF, there is no minidump or macho-o writers.

# pkg/proc/proc_test.go
Add a helper method for collecting line table file references that
does the correct thing for DWARF 5 vs DWARF 4 (in the latter case you
have an implicit 0 entry which is the comp dir, whereas in the former
case you do not). This is to avoid out-of-bounds errors when examining
the file table section of a DWARF 5 compilation unit's line table.
Included is a new linux/amd-only test that includes a precompiled C
object file with a DWARF-5 section that triggers the bug in question.
Fixes#2319
Due to a missing check TestCgoStacktrace2 didn't actually check
anything. Enable it and then skip it on linux/386 and linux/arm64 where
it's broken.

* proc/tests: keep track of tests skipped due to backend problems
Mark tests skipped due to backend problems and add a script to keep
track of them.
* Travis-CI: add ignorechecksum option to chocolatey command
Looks like a configuration problem on chocolatey's end.
