When seeing a line like:
#01 pc 0012ea14 /system/lib/libart.so!libart.so (offset 0x134000)
Treat it like this line instead:
#01 pc 0012ea14 /system/lib/libart.so
This will allow the symbolizer to properly figure out the line numbers.
Bug: 148657674
Test: Ran lines with xxx.so!xxx.so lines and verified that they decode.

* Usage note and help for command flags in the script.
* Run cargo -v multiple times and collect output in cargo.out.
* Use target.tmp as temporary working directory.
* Generate multiple Android.bp files into subdirectories.
* Simplified package names, without version number.
* Merged Android.bp modules.
* Use --device flag to generate both host and device build targets
in a combined module.
* Use --tests flag to generate rust_test modules, with auto_gen_config,
and multiple unit tests merged in one module.
* Generate cc_library_static modules for rust packages that call
'cc' and 'ar' to build static C/C++ libraries.
* Use the --vv flag to call cargo with -vv.
* Limitations:
* Cargo.toml and its build scripts might need fix for Android first.
* Depending on user given cargo parameters.
* TODOs:
* Handle multiple crate types in one rustc command line.
* Smart merge of host and device rust_test modules,
to handle device tests that depend on dynamic libraries.
* Handle special Rust packages that use only build scripts
and C/C++ compilers to generate included files.

On Ubuntu 18.04, /bin/sh is symlinked to dash. Executing codegen under
dash results in the following error:
codegen: Syntax error: "(" unexpected
To prevent this, explicitly use bash.

gdb looks for an executable's dynamic linker using the PT_INTERP setting
from the executable. That value can be various things:
- /system/bin/linker[64]
- /system/bin/linker_asan[64]
- /system/bin/bootstrap/linker[64]
Currently, only the bootstrap linker is available in the sysroot/symbols
directory. The ordinary and ASAN linkers are symlinks on the target and
are missing from the sysroot (aka symbols) directory.
Use the executable's PT_INTERP value to find the symbolized linker binary
and add it to the solib search path. If necessary, copy or pull a linker
binary.

This adds a new --setup-forwarding {gdb|vscode} flag that will make
gdbclient.py (1) setup the port forwarding needed to connect to a
remote process and (2) print the commands/configuration needed to use
the frontend of your choice to run the debugger. Currently it supports
gdb and visual-studio code. In order to avoid using up all the ports
the gdbclient.py program will not exit until directed by user input,
holding the ports open until this occurs.
To use:
```
% ./development/scripts/gdbclient.py -n com.android.contacts --setup-forwarding vscode
