FIPS-compliant CVD signing and verification

Add X509 certificate chain based signing with PKCS7-PEM external
signatures distributed alongside CVD's in a custom .cvd.sign format.
This new signing and verification mechanism is primarily in support
of FIPS compliance.

Fixes: https://github.com/Cisco-Talos/clamav/issues/564

Add a Rust implementation for parsing, verifying, and unpacking CVD
files.

Now installs a 'certs' directory in the app config directory
(e.g. <prefix>/etc/certs). The install location is configurable.
The CMake option to configure the CVD certs directory is:
  `-D CVD_CERTS_DIRECTORY=PATH`

New options to set an alternative CVD certs directory:
- Commandline for freshclam, clamd, clamscan, and sigtool is:
  `--cvdcertsdir PATH`
- Env variable for freshclam, clamd, clamscan, and sigtool is:
  `CVD_CERTS_DIR`
- Config option for freshclam and clamd is:
  `CVDCertsDirectory PATH`

Sigtool:
- Add sign/verify commands.
- Also verify CDIFF external digital signatures when applying CDIFFs.
- Place commonly used commands at the top of --help string.
- Fix up manpage.

Freshclam:
- Will try to download .sign files to verify CVDs and CDIFFs.
- Fix an issue where making a CLD would only include the CFG file for
daily and not if patching any other database.

libclamav.so:
- Bump version to 13:0:1 (aka 12.1.0).
- Also remove libclamav.map versioning.
  Resolves: https://github.com/Cisco-Talos/clamav/issues/1304
- Add two new API's to the public clamav.h header:
  ```c
  extern cl_error_t cl_cvdverify_ex(const char *file,
                                    const char *certs_directory);

  extern cl_error_t cl_cvdunpack_ex(const char *file,
                                    const char *dir,
                                    bool dont_verify,
                                    const char *certs_directory);
  ```
  The original `cl_cvdverify` and `cl_cvdunpack` are deprecated.
- Add `cl_engine_field` enum option `CL_ENGINE_CVDCERTSDIR`.
  You may set this option with `cl_engine_set_str` and get it
  with `cl_engine_get_str`, to override the compiled in default
  CVD certs directory.

libfreshclam.so: Bump version to 4:0:0 (aka 4.0.0).

Add sigtool sign/verify tests and test certs.

Make it so downloadFile doesn't throw a warning if the server
doesn't have the .sign file.

Replace use of md5-based FP signatures in the unit tests with
sha256-based FP signatures because the md5 implementation used
by Python may be disabled in FIPS mode.
Fixes: https://github.com/Cisco-Talos/clamav/issues/1411

CMake: Add logic to enable the Rust openssl-sys / openssl-rs crates
to build against the same OpenSSL library as is used for the C build.
The Rust unit test application must also link directly with libcrypto
and libssl.

Fix some log messages with missing new lines.

Fix missing environment variable notes in --help messages and manpages.

Deconflict CONFDIR/DATADIR/CERTSDIR variable names that are defined in
clamav-config.h.in for libclamav from variable that had the same name
for use in clamav applications that use the optparser.

The 'clamav-test' certs for the unit tests will live for 10 years.
The 'clamav-beta.crt' public cert will only live for 120 days and will
be replaced before the stable release with a production 'clamav.crt'.
