* The emitted esil for jalr was incorrect in the case where `rd` and
`rs1` are equal, since then `rs1` is written to as `rd` before adding
the immediate.
For example, `jalr ra ra 0x42` was lifted to the following esil:
4,$$,+,ra,=,ra,66,+,pc,=
While this does correctly set rd to the return address after the call,
pc is not correctly set according to `pc <- ra + 0x42`, but instead
`pc <- pc + 4 + 66`.
This commit flips the order of setting `pc` and `rd`, so that `rd` is
read from before it is written to.
* According to the spec, the auipc instruction's immediate is a
20-bit upper immediate, which means it should be left-shifted
by 12 similar to the lui instruction:
> AUIPC forms a 32-bit offset from the 20-bit U-immediate,
> filling in the lowest 12 bits with zeros, adds this offset
> to the address of the AUIPC instruction, then places the
> result in register rd.
* Add support for listing parsers, bits and add `Lp` command
* Populate option fields for `asm.parser` and `asm.bits` instead of printing, now tab autocompletion works
* Use `r_str_newf()` function instead of snprintf for updating `asm.bits`
* Add test case for Lp command
kvm_openfiles failed to open /dev/mem without root on fbsd, the special value
"/dev/null" should be used as non root since we don't directly access kernel memory.
* Support more output modes for class inheritence graph.
* Refactor codexrefs and importxrefs graphs.
* Add ag_w for the commands using new mechanism.

* Support demangling function types inside templates
* Support demangling array types inside templates
* Support demangling empty templates
* Support demangling compiler generated statics
* Support demangling thunk functions
* Unwrap quoted strings when passing args to newer handlers ##newshell
When a user wraps an argument, it means like in SH that he wants the
command to consider the argument as one single arg, even if composed by
multiple words. The same applies for r2newshell. So far we did not
unwrap quoted strings to maintain compatibility with old shell, but
doing this unwrapping is one of the nice feature of newshell.
* Add tests for quoting/unquoting
* Adjust tests with `w` for newshell/oldshell
* Fix asm/anal IT block for ARM
* Fix indent + missing spaces
* Fix ARM asm patch breaking test

* Changed to RIOBind + fix code based on comments

* Convert R_CMD_DESC_TYPE_GROUP to INNER
* Avoid confusing "group_" prefixes by splitting cmddesc ##newshell
Create "group" command descriptor and give them their own help, to avoid
dupping fields such as group_summary, group_args_str, etc. By having a
separate help structure for the grouping node we make the cmd_api code
easier because it doesn't need to distinguish between
group_summary/summary, group_args_str/args_str, etc. and we avoid few
bytes for each command descriptor help structure, since most of them
did not use group_* fields.
* Other simplification in cmd_api due to split GROUP/exec cb.
* Handle R_CMD_DESC_TYPE_GROUP in r_cmd_call_parsed_args

Merge sort uses cmp (a, b) < 0 for its first test branch, and insertion
sort cmp (a, b) > 0 ; which means the 0 boundary goes in one case in one
branch, and in the other sort function in the other branch.
It makes it possible to support compare function that return true/false
instead of -1/0/1; although this isn't an acceptable use of
RListComparator, this prevents future bugs from appearing, because this
works with insertion sort, but not merge sort.
The main advantage of this patch is that both sort functions should sort
equal elements the same way. This stability is important for zignatures
for example.
Do not use #include <capstone/..>
This ensures compatibility with both capstone v3 and capstone as
installed on most distributions, where the pkg-config file of capstone
already adds -I/usr/include/capstone (with that dir directly containing
the headers).
* Correctly get the address of the PLT entry for a symbol. If the symbol
was not yet added to the .got.r2 section, then take the first available
address (vaddr), otherwise retrieve it from the hashtable.
* Avoid showing wrong relocations when relocations are already replaced
libr.a is built with all the files required to build against r2, so that
includes also SDB. As SDB already has a file named json.c, the new json
parser in r_util collides with it.
