PPC uplifting to RzIL (#2823)
* Print a warning if config for VM was NULL.
* Add warning if register is not added to VM due to overlap.
* Update PPC register profile.
* Add vector and float registers. As well as some control and system registers.
* Enable to write values 4bit registers.
* PPC: Uplift most common instructions.
* Print warning if reserved SPR instruction is encountered.
* Update PC/LR addresses and add ca32 writes.
* Write cache needs to get flushed so load and store tests don't share the same memory.
* Add missing T/F branch mnemonics.
* Add Move to/from CR/CR0-7
* Fix TA address calculation for branch instructions.
* Add branch tests for branch mnemonics.
* Add XNOP
* NOP cache touch instructions.
* Add undocumented ATTN instruction to the not_implemented group.
* Add isel instruction.
* Implement CRCLR, CRSET, CROR.
* Add CNTLZ instructions.
* Add mcrf instructions.
* Add inacive test for cmpb.
* Add Load bytes reverse instructions.
* Add test and add address alignment to dcbz.
* Add eqv test
* Correct DIV and MUL operations
* Add div tests.
* Add tests and correct MT/MFXER
* Remove register ca32, ov32
* Remove explici setting of cr register because QEMU does not do it. Otherwise we get a mismatch in the trace
* Simplify carry set for add and sub. Sub instructions are exclusivly defined with addition. Hence no sub case needed.
* Unify BD and fix branch instructions. Fix: Check the single bit not the cr reg
* Document Conditional branches and replace NOPs with EMPTY
* Add mulli instruction to double word instructions.
* Fix ca set for shift instructions:
* ca value had to be determined before the shift happened. The wrong ca value was calculated if the src and target reg were the same.
* Replace NOP wit EMPTY.
* Use MSB isntead of SLT.
* Brought fixup of ADD and SUB instructions: The add and sub instructions had several issues which let to incorrect execution.
* The carry was incorrectly if three add operations happened (only the last add were checked, not both).
* The carry was incorrectly set if the src and target register matched.
* Same applies for the CR bit.
* It was too complex. Several local variables were introduced for this.
* Set result in local var, since it would change if src and target reg are the same.
* Remove MTMSR and MFMSR since it is too complex and untestable currently.
* Use unsigned int for shift. Otherwise the 0x1c shift produces a runtime error since 0xf is int as default.
* Fix mtxer: Only write flag bits.
* Let NOT_IMPLEMENTED macro return NULL.
* Mark st[wd]cx and l[wd]cx as not implemented.
* Increase dcache_line_size to 128 bytes.
* Fix cntlz for ppc32. m was set incorrectly, since it is 0 not 32 for 32bit cpus.
* Fix isel: Use op.crx reg instead of imm.
* Unify helper function names: Prependnig `ppc_` mark as IPI
* Add more "Move to SPR" cases.
* MULLI opeartes only on double word on 64bit CPUs.
* Most registers are now assigned the control register type and no longer show up in the ar command.
* Fix xor if dest and src registers match by saving result in local var.
* Fix BE/LE issue for Load BRX instructions.
* Fix shifts: Use only lower 6bits of n.
* User Pure local variables for ROT macros.
* Fix rldimi instructions.
* n was not inverted.
* more than 6 bits of n could be used
* Add 32bit emulateme tests.
* Add 64bit emulateme tests.
* Determine lg(v) in inline function.
* Calculate CR bit in C not in the VM.
* Check if `~mask = 0` and skip mask calculation if yes.
* Check for `sh == 0` and skip rotations where possible.
* Remove `la` instruction. `la` is a mnemonic for `addi`.
* Remove SPR instructions which are not supported by QEMU or not traced yet. For most set/read SPR instructions QEMU segfaults.


In case of SPR 1 (xer), 8 (lr) and 9 (ctr) the assembler resolves them to their mnemonics (mtxer, mtlr etc.). This means the code here is never reached.
To test the get_xer code MFXER was added again. The rz-tracetests will fail for this instructions (due to missing ca32, ov32). But this case is covert in an issue.

Rewrite ar and dr with newshell (#2006)
* Show group-level details of commands

Details can be defined at either a group command or its subcommand of
the same name. If define on group-level it will also be shown in the
group help without needing ??.

* Fix > $ redirection for errored command and leak

* Rewrite ar and dr commands with newshell

Breaking changes:
ar* => arf, ar- => arf-, ar. => ar*
ar, => art, ar? => arq
ar0 => ara0, arb => arab, ars => araS
arC => arpC
arn => arR
art => arT
arf => arF
Removed: drm, aer

88eaf90b9c Fix Confusion of Reloc Source and Target Addresses
old RzBinReloc.vaddr contained either the reloc address or
the target address, depending on how the bin was loaded.
Now there are two members and dedicated query function for each.
