6ef7aa8743 service: move some type conversions from service/debugger to rpc pkgs
Move the conversion of some 'proc' types from service/debugger into
service/rpc1 and service/rpc2. The methods of
service/debugger.(*Debugger) are also used by service/dap which
requires these types to be converted differently and converting them
twice is inefficent and doesn't make much sense.

proc/*,service: replace uses of uintptr with uint64 (#2163)
Since proc is supposed to work independently from the target
architecture it shouldn't use architecture-dependent types, like
uintptr. For example when reading a 64bit core file on a 32bit
architecture, uintptr will be 32bit but the addresses proc needs to
represent will be 64bit.

7555d1c063 cmd,proc,terminal,debugger: Support default file descriptor redirects
Adds features to support default file descriptor redirects for the
target process:

1. A new command line flag '--redirect' and '-r' are added to specify
   file redirects for the target process
2. New syntax is added to the 'restart' command to specify file
   redirects.
3. Interactive instances will check if stdin/stdout and stderr are
   terminals and print a helpful error message if they aren't.

f90134eb4d proc: prevent internal breakpoint conditions from failing
An internal breakpoint condition shouldn't ever error:
* use a ThreadContext to evaluate conditions if a goroutine isn't
  available
* evaluate runtime.curg to a fake g variable containing only
  `goid == 0` when there is no current goroutine

proc: fix support for AVX registers (#2139)
Recent changes to the way registers are handled broke reporting of AVX
registers (i.e. YMMx). This change restores the functionality by:

- concatenating the higher half of the YMMx registers to their
  corresponding XMMx lower half (YMMx registers do not have an
  independent DWARF register number)
- modifying the formatSSEReg function to handle them when they are
  present.

Go 1.15 support (#2011)
* proc: start variable visibility one line after their decl line

In most cases variables shouldn't be visible on their declaration line
because they won't be initialized there.
Function arguments are treated as an exception.

This fix is only applied to programs compiled with Go 1.15 or later as
previous versions of Go did not report the correct declaration line for
variables captured by closures.

Fixes #1134

* proc: silence go vet error

* Makefile: enable PIE tests on windows/Go 1.15

* core: support core files for PIEs on windows

* goversion: add Go 1.15 to supported versions

* proc: fix function call injection for Go 1.15

Go 1.15 changed the call injection protocol so that the runtime will
execute the injected call on a different (new) goroutine.

This commit changes the function call support in delve to:

1. correctly track down the call injection state after the runtime
   switches to a different goroutine.
2. correctly perform the escapeCheck when stack values can come from
   multiple goroutine stacks.

* proc: miscellaneous fixed for call injection under macOS with go 1.15

- create copy of SP in debugCallAXCompleteCall case because the code
  used to assume that regs doesn't change
- fix automatic address calculation for function arguments when an
  argument has a spurious DW_OP_piece at entry

tests: fix flakiness of of TestIssue414 on windows (#2082)
Recent change #2061:

292f5c69f0c769fd32c2e8b1e7153b56e908efd7
proc: step into unexported runtime funcs when already inside runtime

means that TestIssue414 (which tries to step repeatedly until the
program exits) can now steps through way more runtime code than it ever
did before. This causes this test to occasionally fail. Stepping
blindly through runtime code has never been particularly safe as the
runtime can switch to a different goroutine causing Delve to misbehave.

This change restores the previous behavior of TestIssue414 where Step
behaved like Next inside runtime code.

gdbserial: ensure registers are loaded in SetDX/SetSP/SetPC (#2054)

terminal/command: Add 'reload' command (#1971)
* terminal/command: Add 'reload' command

These changes add the 'reload' command, which allows us to rebuild the project
and start the debugging session again. Currently, if the project's code is
updated while debugging it, Delve shows the new source code, but it's still
running the old one. With 'reload', the whole binary is rebuilt, and the
process starts again.
