Add a CLI compatible Rust implementation of pvattest-C.
- All (non-experimental) options are supported and work exactly as in
the C implementation. For some options/parameters new variants are
available.
- `perform` now also accepts positional arguments, while keep accepting
-i and -o that was mandatory in the C implementation.
- `version` may also be a command instead of an option now.
- -V is deprecated
- -v increases verbosity instead of showing the version
- all experimental options are dropped

Renames pv crate to s390_pv and pv_core to s390_pv_core. pv was already
taken on crates.io.
Bump the versions of all crates to 0.10.0. From now on we follow Semver
compatibility rules when it comes to updates. patch-level updates will
not introduce any backwards incompatible changes. For now all crates in
this directory will have the same version number. A version update may,
therefore, not add any new things.
Library users in this repository still use the non prefixed names and
rename the crate in the Cargo.toml. Doc-tests have to use the new name
however.
Add some Cargo metadata to the Cargo.toml.

Prepare pv & pv_core crates to be released on crates.io:
* Remove any unused API to stay flexible
* Remove utils dependency
* Move cli, tmpfile and version utilities to local utils crate
* Use the new utilities in the pv tools
* Rename Secret into Confidential to avoid confusion of Secret (now
Confidential) and AddSecret requests.
* Move the uvsecret module out of the request module and change the name
to secret.
* Cleanup dependencies
* Precise and correct minimal dependency versions
* Inline `Aes256Key::from_digest`
The cleanup ensures that the code also compiles with the dependencies
resolved to their minimal versions using:
$ cargo +nightly -Z minimal-versions update
$ cargo build

Add a new tool named chpstat that can be used to view channel-path
statistics such as utilization and I/O throughput, and to query and

Note: Channel-path statistics are only available on systems running in
an LPAR or DPM partition.
When run without further options, data for all channel-paths is
displayed repeatedly with a 5 second delay in table format.

Add helper functions for converting structured key-value data into
different formats such as JSON, text pairs, and CSV.
Using these functions the resulting output format can be dynamically
configured at run-time without the need to duplicate output-generating
code for each format type. Also format-specific requirements such as
quoting, indentation, and comma-placement are automatically taken care
of.
Basic API calling sequence:
util_fmt_init() => Select output format
util_fmt_obj_start() => Start a new object or list
util_fmt_pair() => Emit a key-value pair
util_fmt_obj_end() => End the most recent object or list
util_fmt_exit() => Cleanup
Notes:
- Supported data elements are objects, lists and key-value pairs
(mappings)
- Scalars are only supported as part of a mapping

By default, files opened via fopen are block-buffered. As a result,
I/O errors that occur during file write operations via util_file_write_*
are silently ignored because fputs() only buffers data while actual I/O

library call.

Steps to reproduce: Prepare some target disk for IPL, specifying

located on another disk. Don't specify "-a" option.
Actual result: Installation succeeded (resulting in unbootable setup)
Expected result: "Error: Could not add image file 'IMAGE_NAME': File

The problem is in incorrect evaluation of device number(dev_t) where
the image is located by the function add_component_file_range() in
case when target parameters are specified by user.

This patch fixes a bug in disk_get_info()
Steps to reproduce: Prepare a SCSI disk for IPL, specifying an image
("-i IMAGE_NAME") located on DASD and a target directory ("-t /mnt")
located on SCSI (dm). Don't specify "-a" option.
Actual result: Installation succeeded (resulting in unbootable setup!)
Expected result: "Error: Could not add image file 'IMAGE_NAME':
File is not on target device".
The problem is in incorrect evaluation of device number (dev_t) of
the device, where the image file is located, by the function
add_component_file_range(). To evaluate it, disk_get_info() is called
with the structure job_target_data (passed as the second argument)
previously completed by disk_get_info() called earlier to evaluate
parameters of the specified target device (SCSI dm) by the function
prepare_build_program_table_file(). Since the targetbase is already
set in the passed job_target_data (by the first call), in the second
call the source type is evaluated as "source_user", so the number of
the device where the image is located is calculated by the base SCSI
disk, which is incorrect.
Fixup: Rework disk_get_info(): introduce a dedicated function to
evaluate source type not depending on the job_target_data content.
Implement the core procedure as a switch by the evaluated source
type.

Actual result: "Run /lib/s390-tools//zipl_helper.device-mapper /mnt

Expected result: "Run /lib/s390-tools//zipl_helper.device-mapper 253:4

The problem is in incorrect calculation by disk_get_info()
parameters for @device associated with the image file. Specifically,
@target->bootmap_dir is passed to the script, which is wrong.
Fixup: Get rid of bogus branching in disk_get_info() in case when
target parameters are evaluated in "source_script" mode. Always pass
major and minor of the @device (whose parameters to be calculated)
