a8b13d79bf Add tests for relaxed CRL-CA name comparison
This commit introduces variants test-ca_utf8.crt,
test-ca_printablestring.crt and test-ca_uppercase.crt
of tests/data_files/test-ca.crt which differ from
test-ca.crt in their choice of string encoding and
upper and lower case letters in the DN field. These
changes should be immaterial to the recovation check,
and three tests are added that crl.pem, which applies
to test-ca.crt, is also considered as applying to
test-ca_*.crt.

The test files were generated using PR #1641 which
- adds a build instruction for test-ca.crt to
  tests/data_files/Makefile which allows easy
  change of the subject DN.
- changes the default string format from `PrintableString`
  to `UTF8String`.

Specifically:
- `test-ca_utf8.crt` was generated by running
      `rm test-ca.crt && make test-ca.crt`
   on PR #1641.
- `test-ca_uppercase.crt`, too, was generated by running
      `rm test-ca.crt && make test-ca.crt`
   on PR #1641, after modifying the subject DN line in the build
   instruction for `test-ca.crt` in `tests/data_files/Makefile`.
-  `test-ca_printable.crt` is a copy of `test-ca.crt`
   because at the time of this commit, `PrintableString` is
   still the default string format.

6e1adee42b Regenerate test files
Previous commits have added or modified build instructions for
server1*, server2*, server5*, test-ca*, cli-rsa* in the Makefile
tests/data_files/Makefile, or the apps they invoke have been changed.

This commit regenerates those files to make sure they are in match with
the build instructions.

  ssl_server2: add buffer overhead for a termination character
  Add missing large and small packet tests for ssl_server2
  Added buffer_size and response_size options for ssl-server2. Added appropriate tests.

Solving a conflict in tests/ssl-opt.sh: two set of tests were added at the
same place (just after large packets):
- restartable ECC tests (in this branch)
- server-side large packets (in development)

Resolution was to move the ECC tests after the newly added server large packet
ones.

95c5575e12 check-files: exclude .git and third-party files
Exclude ".git" directories anywhere. This avoids spurious errors in git
checkouts that contain branch names that look like a file
check-files.py would check. Fix #1713

Exclude "mbed-os" anywhere and "examples" from the root. Switch to the
new mechanism to exclude "yotta/module". These are directories where
we store third-party files that do not need to match our preferences.

Exclude "cov-int" from the root. Fix #1691

427df37f84 Don't try to disable ASLR
We don't need to disable ASLR, so don't try. If gdb tries but fails,
the test runs normally, but all.sh then trips up because it sees
`warning: Error disabling address space randomization: Operation not permitted`
and interprets it as an error that indicates a test failure.

65593d2ddd rsa: pss: Add no possible salt size tests
Add signing tests with 528-bit and 520-bit RSA keys with SHA-512. These
selections of key and hash size should lead to an error returned, as
there is not enough room for our chosen minimum salt size of two bytes
less than the hash size. These test the boundary around an available
salt length of 0 or -1 bytes.

The RSA keys were generated with OpenSSL 1.1.1-pre8.

80d99ea038 rsa: pss: Extend tests for variable salt length
Since we wish to generate RSASSA-PSS signatures even when hashes are
relatively large for the chosen RSA key size, we need some tests. Our
main focus will be on 1024-bit keys and the couple key sizes larger than
it. For example, we test for a signature generated using a salt length
of 63 when a 1032-bit key is used. Other tests check the boundary
conditions around other key sizes. We want to make sure we don't use a
salt length larger than the hash length (because FIPS 186-4 requires
this). We also want to make sure we don't use a salt that is too small
(no smaller than 2 bytes away from the hash length).

Test RSASSA-PSS signatures with:
 - 1024-bit key and SHA-512 (slen 62)
 - 1032-bit key and SHA-512 (slen 63)
 - 1040-bit key and SHA-512 (slen 64)
 - 1048-bit key and SHA-512 (slen 64)

The tests also verify that we can properly verify the RSASSA-PSS
signatures we've generated.

We've manually verified that OpenSSL 1.1.1-pre8 can verify the
RSASSA-PSS signatures we've generated.

    Verified OK

We've also added a new test that ensures we can properly validate a
RSASSA-PSS 1032-bit signature with SHA-512 generated by OpenSSL. This
has been added as the "RSASSA-PSS Verify OpenSSL-generated Signature
1032-bit w/SHA-512" test. The signature to verify was generated with the
following command line.

    $ cat message.bin | openssl dgst -sha512 -sigopt rsa_padding_mode:pss -sigopt rsa_pss_saltlen:63 -sign rsa1032.pem > valid.bin

The RSA private keys used by these tests were generated with OpenSSL
1.1.1-pre8.

3725bb2d6d rsa: pss: Enable use of big hashes with small keys
It should be valid to RSASSA-PSS sign a SHA-512 hash with a 1024-bit or
1032-bit RSA key, but with the salt size being always equal to the hash
size, this isn't possible: the key is too small.

To enable use of hashes that are relatively large compared to the key
size, allow reducing the salt size to no less than the hash size minus 2
bytes. We don't allow salt sizes smaller than the hash size minus 2
bytes because that too significantly changes the security guarantees the
library provides compared to the previous implementation which always
used a salt size equal to the hash size. The new calculated salt size
remains compliant with FIPS 186-4.

We also need to update the "hash too large" test, since we now reduce
the salt size when certain key sizes are used. We used to not support
1024-bit keys with SHA-512, but now we support this by reducing the salt
size to 62. Update the "hash too large" test to use a 1016-bit RSA key
with SHA-512, which still has too large of a hash because we will not
reduce the salt size further than 2 bytes shorter than the hash size.

The RSA private key used for the test was generated using "openssl
genrsa 1016" using OpenSSL 1.1.1-pre8.
