* service/api: Removed unused fields of service/api.Function
* proc/eval: Set return variable name to input expression
* all: fine-grained control of loadValue for better variable printing
Makes proc.(*Variable).loadValue loading parameters configurable
through one extra argument of type LoadConfig.
This interface is also exposed through the API so clients can control
how much of a variable delve should read.
* proc: add tests for command-line arguments
adds tests to make sure command-line arguments are passed to Launch() properly
* proc_windows: pass command-line arguments to CreateProcess()
build command-line arguments according to how the standard library does it and pass the command line along to the actual syscall on Windows.
see discussion in #479
* proc: better testing of cmd-line arguments
* proc_windows: fix a possible error-case with passing just 1 argument
previously, the command line pointer passed to sys.CreateProcess was empty, if we had 0 parameters (len(cmd) == 1, as cmd[0] is the executable, so no cmdlineGo would be created, while with any argument it would as len(cmd) > 1). This might cause problems down the road, so make sure we include the command line every time, even if it seems to work without.
* proc: improve testing of command-line arguments
test that arguments with spaces are passed on correctly and DRY failure/success condition checking in the args test
- made GoroutineStacktrace a method of struct G
- made stacktrace a method of StackIterator
- renamed StackIterator to stackIterator
- factored out logic to obtain a stackIterator from a goroutine that's
used by both (*G).Stacktrace and by (*G).UserCurrent
Unrelated to conversion, I have also changed (*Thread).readMemory
to return only first count bytes of memory just as advised
by ReadProcessMemory.

Step disassembles the current instruction, if it is a CALL sets a
temp breakpoint inside the called function, after the prologue and
calls Continue.
Fixes#332
- Unlike FunctionEntryToFirstLine can skip the prologue on functions
that are defined on a single line, either because they weren't
formatted or because they were autogenerated
- Can skip the prologue on most functions when setting a breakpoint
with the filename:line syntax
Fixes#396
1. A running goroutine is by definition not parked waiting for a
chan recv
2. The FDE end address is intended to be exclusive, the code
interpreted as inclusive and sometimes ended up setting a breakpoint
on a function other than the current one.
Past the maximum recursion depth maps shouldn't be loaded at all,
adding map children and not loading them breaks assumptions in
the prettyprinter.
Fixes#406
If uninitialized memory is read loadArrayValues could try to call
cacheMemory with a negative size, which could cause a 'makeslice:
len out of range' panic.
Fixes#354 (partial)
Typedefs that resolve to slices are not recorded in DWARF as typedefs
but instead as structs in a way that there is no way to know they
are really slices using debug/dwarf.
Using golang.org/x/debug/dwarf instead this problem is solved and
as a bonus some types are printed with a nicer names: (struct string
→ string, struct []int → []int, etc)
Fixes#356 and #293
Instead of the `step` command single stepping every thread, instead only
step the "current" thread. This fixes a few issues surrounding single
stepping, and simplifies the logic. The original concerns around only
stepping a single thread (with regard to coordination) are invalid and
generally non-issues.
Location specifiers starting with '*' can be followed by any
expression supported by the evaluator.
The expression should evaluate to either an integer (which will be
interpreted as an address) or to a function pointer (which will be
dereferenced to get the function's entry point).
