This commit changes several settings. The main reason is to have them
contained in one search group, and not spread over the search and string group.
This becomes important with the search refactor, since the search is now also
more contained in a single module and can make use of the more settings.
- Remove str.search.max_uni_blocks - Effectively a metric the user should not know about; adds too much complexity. Also not documented.
- str.search.encoding -> str.encoding - Valid for all string interpretations.
- str.search.max_threads -> search.max_threads - This is a general setting for the search now.
- str.search.raw_alignment -> search.str.raw_alignment - Unify settings (only used for RzBin search.).
- str.search.min_length -> search.str.min_length - Unify settings.
- str.search.buffer_size -> search.str.max_length - Unify settings.
- str.search.max_region_size -> search.str.max_region_size - Unify settings.
- str.search.check_ascii_freq -> search.str.check_ascii_freq - Unify settings.
Part 3/9. Likely won't build in between parts.

The only place where this field was set to a non-zero value was the now
removed fb command, and it was never used for anything sensible. Thus it
is safe to remove.

- Support for parse DWARF section "debug_loclists", "debug_ranges", "debug_rnglists"
- Partial support for eval DWARF expr_loc
- Support for anonymous Type, function variable, struct member
- Cache all DWARF information in `RzAnalysisDebugInfo` and remove `SDB` based caching.

Variables on the stack are not identified by bp/sp+<offset> anymore, but
by their address from the bottom of the stack frame (RzStackAddr),
independent of how they are accessed.
So now there are only two kinds of variables: stack and register.
This required some major refactoring and other changes:
* RzAnalysisVar.isarg was removed. Whether a variable is an argument is
now specified implicitly by its storage location.
* Varsub of struct fields had to be rewritten so fields can be queried
by arbitrary stack addresses using the recently introduced sp
tracking, as the old approach to fill a list with all fields would not
work anymore.
* analysis.vars.stackname was removed, new behavior is more similar to
this being true before.
* Variables will not be created at stack+0 now, because the return
address is there. Before, vars were only created sometimes in such
cases.
* Variables created from bp offsets in x86 are not deleted anymore if
the function's bp_frame is false (see removed
rz_analysis_function_delete_vars_by_kind(fcn,
RZ_ANALYSIS_VAR_KIND_BPV); calls). This may lead to some
false-positive detected variables. Whether this really is a practical
issue is yet to be seen. At least there are no meaningful tests that
are broken by this.
* Applying variables from dwarf needed some fixes for determining the
correct stack locations of variables in order to write meaningful
tests. The handling is still not entirely correct for all
possibilities of dwarf info, but at least the changed/added test cases
are right and serve as a reference for future changes.
* Projects version 11 is introduced.
* afvb commands have been removed, afvs now handles all stack vars.
The stack pointer was previously already tracked during analysis for
variables and their accesses, but not stored in any sensible form for
further use. RzAnalysisBlock.stackptr and parent_stackptr were used in
some places, but they had no evident meaning.
Now we store the sp at the entry of a basic block and the difference
from that for every instruction inside the block to allow for efficient
querying of the sp value at arbitrary analyzed addresses.
RzAnalysisFunction.stackptr is now deprecated as its previous use was
primarily as a temporary accumulator, which is now handled locally, but
full removal of it would go beyond the scope here.
asm.stackptr visualizes both the absolute sp value and the delta of each
instruction in disassembly.
Changes in librz/analysis/p fix some test cases with the new tracking.
Introduces project version v10 with sp_entry/sp_delta instead of
stackptr/parent_stackptr.
Even though many of the migrations were trivial, for all previous
versions X it is important to have both tests for X->X+1 migrations
and loading X in current rizin.
See leading comment in test_project_migrate.c for details.
Leaks detected by these tests were also fixed.
* Add support for: v5-v68+HVX, System instructions/register; Change plugin design to monolithic; Basic ELF-reloc patching.
- Update instruction set to v5-v67 + HVX.
- Introduce monolithic plugin architecture to reverse opcodes in the same functions.
- Analysis and Asm functionality was previously seperated and let to inconsistensies and incorrectly reversed opcodes.
- Add missing system instructions and registers.
- Enable search for immediates.
- Mark packets of instructions.
- Set more analysis data in RzAnalysisOp.
- Add basic ELF-reloc patching.
- Fix several disassembly and analysis bugs.
- Jumps were not aligned to packet begin.
- Endloop packets were not marked as such.
- Rs.New registers were incorrectly disassembled.
- Calling convention was out of date.
- Add several formatting configs for the produced disassembly.
- Dis/Enable UTF-8.
- Print or omit # prefix of immediates.
- Print signed immediates as signed or unsigned integers.
- Removed oldshell version of `t` (types) commands
- Removed `tk` command because types storage switched to the hashtable
- Added `tfc` command to show the calling convention of the function or set it
- Added `tsl` (RZ_OUTPUT_MODE_LONG) to show structure members' sizes and offsets
- Added `tul` (RZ_OUTPUT_MODE_LONG) to show union members' sizes
- Switched the types storage to the hashtable instead of SDB
- Added load and export from/to SDB for standard type libraries and serialization for Projects
- Changed all `char *type` occurences to the proper `RzType`
- Added `RzCallable` type for the function/class method types
- Changed all function types API to use the `RzCallable` API
- Switched the function types (`RzCallable`) storage to the hashtable instead of SDB
- Added a connection between `RzAnalysisFunction` and `RzCallable` - `rz_analysis_function_derive_type()` API function to derive new `RzCallable` type from the `RzAnalysisFunction` even if it doesn't exist in the RzTypeDB.
- Moved type links to the RzAnalysis where they belong
- Removed TCC and MPC-based parsers
- Added Tree-Sitter-based parser for C grammar (see `librz/type/parser/*`)
- Reworked type databases in `librz/analysis/d/` to be consistent with C standard, libc, platform-specific definitions
- Switched the type links from `char *` to `RzType`
- Switched the type links from SDB to the hashtable
- Added concept of the "type paths", e.g. `a.b[20].c` where `b` is a member of `a` (`a` is either structure or a union) and `c` is a member of `b`, and `b` is an array where we take 20-th element.
- Added concept of the typeclasses (a bit similar to Haskell) for numerical types: `None` (the most generic one), `Num` (includes `Integral` and `Floating`), `Integral` (includes `Signed Integral` and `Unsigned Integral`), `Floating`.
- Added concept of type equality (`rz_types_equal(a, b)` API function)
- Added Doxygen documentation to every API function in the `librz/type/*`.
- Updated the project format from **V2** to **V3**, added migration.
