This adds a workaround for the bug described at:
https://github.com/golang/go/issues/25841
Because dsymutil running on PIE does not adjust the address of
debug_frame entries (but adjusts debug_info entries) we try to do the
adjustment ourselves.
Updates #2346
* service: serialize calls to Command API
Wait until the target process has resumed before accepting new calls to
Command. Before this if a 'continue' was immediately followed by a
'halt' the 'halt' could be processed before the 'continue'.

- remove github workflow for testing macOS/amd64 that is now covered by
TeamCity
- fix DeepSource glob patterns to actually match what they are intended
to match (did the interpretation change?)
- disable some cgo tests on darwin/arm64
Delve represents registerized variables (fully or partially) using
compositeMemory, implementing proc.(*compositeMemory).WriteMemory is
necessary to make SetVariable and function calls work when Go will
switch to using the register calling convention in 1.17.
This commit also makes some refactoring by moving the code that
converts between register numbers and register names out of pkg/proc
into a different package.
* Avoid double removal of temp binary
* Add back accidentally removed empty line
* Simplify regex
* Use unique build output directories in test cases
* Recover TestLaunchDebugRequest hidden logging and refine error check
* Special case access-denied error on Windows
* Remove special case for access denied on Windows
* Increase remove delay on Win

* TeamCity: add linux/arm64/tip configuration
So that it can be tested when we make the next-version-support-branch.
* tests: disable failing cgo tests on arm64
When cgo is used the address of the g struct is saved on the special
register TPIDR_EL0. Because executing C code could overwrite the
contents of R28 that normally contains the address of g we should read
it from TPIDR_EL0 instead when runtime.iscgo is set.
Remove OS specific install instructions that all repeat the same thing.
Since `go get ...` is being deprecated (to install executables)
recommend an install procedure that works on all supported versions of
go (`git clone && go install`) but also mention the new `go install`
mode in 1.16.

* Reformat pkg/locspec documentation so that it is formatted correctly
by godoc/pkgsite
* Unexport some types and variables in proc that don't need to be
exported.
* 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.

Both structMember and findMethod implemented a depth-first search in
embedded fields but the Go specification requires a breadth-first
search. They also allowed promotion of fields in the concrete type of
embedded interfaces even though this is not allowed by Go.
Furthermore they both lacked protection from infinite recursion
when a type embeds itself and the user requests a non-existent field.
Fixes#2316
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
The DWARF standard does not say that a DW_ATTR_abstract_origin can only
reference entries that appear before it, this change fixes BinaryInfo
to comply. See #2284 for an example of this happening.
Changs TestClientServer_FullStacktrace and
Test1ClientServer_FullStacktrace to log more information, also removes
code from TestFrameEvaluation that could mask the error.
Updates #2231
