* service/rpccommon: log error for conns rejected by --only-same-user
If no logger is enabled manually write to stderr instead.
Fixes#2209
* logflags: fix style complaints from DeepSource
The test needs to set a breakpoint on main.CallFn after the prologue,
on linux/386 this function does not have any instruction after the
prologue on the function header line because it doesn't need to
allocate space for local variables. Change the fixture so that this
isn't a problem.
This bug results on the test failing a small percentage of the time.

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.

If the process receives a signal (or sends a singal to itself) and then
dies before we can route the signal back to it we still need to
retrieve its exit status.

* service/dap: add "panic" and "fatal error" as stopped reasons
The unrecovered panic and fatal throw breakpoints are not set by the
user. We now check for these special breakpoints and send appropriate
stopped reasons to the client.
* Add getter for StopReason
* Set threadID and stop reason correctly
If there is no selected goroutine, no goroutine ID should be set in
the stopped event.
The stopped reason can be better determined using the process
StopReason.
* Update panic breakpoint on next test to work with Go 1.13 runtime
When running panic.go with Go1.13, the next line that is stepped to
after panic('boom') is the defer function in the runtime package. The
unrecovered panic breakpoint is not hit until after several steps.
The test now steps until the breakpoint is hit, or the program terminates
without hitting the unrecovered panic breakpoint, in which case it fails.
* Skip breakpoint on next test in < Go 1.14
* Add underlying type when printing interface type
* Add todo to remove one level from interface printing

* 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.
* proc: use argument position for addr only when injecting function calls
We can not, in general, use the argument position to determine the
address of a formal parameter, it will not work in presence of
optimizations or inlining. In those cases formal arguments could be
stored in registers.

* dwarf/line: ignore end_of_sequence entry if AllPCsBetween
Go 1.15 (but possibly prior versions of Go too) has a tendency to use
an address in the middle of an instruction for this entry, but if it
was correct it would be after the last instruction of the function
anyway.
This problem manifests especially frequently as a target crash in
TestStepConcurrentPtr on linux/arm64 (~6% of the runs).

* service/*: remove threadID argument of (*Debugger).PackageVariables
Which thread is used doesn't make any difference to the list of package
variables that is returned and this option was only ever used by an old
v1 API call.
* Revert "proc: Find executable should follow symbol links."
This reverts commit 3e04ad0fada0c3ab57caf58bc024e4c0f9a3e01a.
* proc: resolve symlinks when searching for split debug_info if path is /proc/pid/exe
Fixes#2168
During the testing of the core dump generation feature two bugs were
discovered in gdbserial:
1. we don't check that both bytes of the checksum are read, if the
buffer only has one byte we can end up reading only one byte instead
of two and the second byte will mess up the parsing of the next
packet
2. binary encoded packets can start with an 'E' and not be errors, when
using binary responses add an extra check for the lenght of the
response before deciding that the response is an error.
Unfortunately this encoding is inherently ambiguous (we can't
distinguish a 3 byte response starting with 'E' from an error) so
binary requests that lead to short responses should be avoided.
Testing this is complicated, they will be tested implicitly by the
upcoming core dump test.

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.
Updates #2161
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.
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.
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
Fixes#2113
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.
Fixes#2033
Commit 1ee8d5c reviewed in Pull Request #1960 relaxed some tests using
goroutinestackprog but missed others.
Fixes some test flakiness that isn't relevant.
