terminal,service,proc/*: adds dump command (gcore equivalent) (#2173)
* 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.

proc: use CPUID to determine maximum size of XSAVE area (#2256)
the maximum size of the Xsave area was previously hardcoded but the
CPUID instruction can be used to determine its maximum size.

pkg/proc,service: support linux/386 (#1884)
Implement debugging function for 386 on linux with reference to AMD64.
There are a few remaining problems that need to be solved in another time.

1. The stacktrace of cgo are not exactly as expected.
2. Not implement `core` for now.
3. Not implement `call` for now. Can't not find `runtime·debugCallV1` or
   similar function in $GOROOT/src/runtime/asm_386.s.

Update #20

be98a8503c proc/native: separate amd64-arch code
As proc/native is arch related, it should move some functions to arch-relate file. And this patch can help us to separate the architecture code, make code tidy. So that the merge of arm64 code later will not cause chaos.(#118)
