For debug purposes.

Example:
  sh ./runtest.sh dgst pkcs8

Run `make tcl_tests' to run the tests. Tests report success state to
make. Tests aren't run by default because of too many failures, yet.

- Remove emacs coding: cp1251 tag
- Change stats file encoding to utf-8
- Change packages source to have -encoding utf-8
- Run tclsh with -encoding utf-8
- Make `proc rus' noop.

This will make Tcl automatically translate scripts output from utf-8 to
system encoding.

All source files are converted from cp1251 to utf-8.

make tests against openssl-stable-1.1.1

Even though it is not recommended by R 1323565.1.023-2018 fill
digestParamSet field for 512-bit curves Test, TC26-A, TC26-B because old
cryptoproviders expect this field to be present.

travis-ci: enable coverity scan

Fix leaks in priv_encode_gost()

Issues/174

This `if' statement is redundant since ce40d60d ("Bugfix.")

get_gost_engine_param() have no side effects and `param' is set to
`gost_cipher_list' only if already equal to `gost_cipher_list'.

`param' is used unconditionally in pkey_GOST_ECcp_encrypt() so we can
unconditionally check (vs in any particular `if' branch) for it's being
non-NULL. This is similar to how pkey_GOST_ECcp_decrypt() works with
`param'.

Closes #174.

Fixes #180

For Grasshopper OMAC_ACPKM, OMAC and MAGMA, support XOF

XOF (eXtendable-Output Function) is supported in OpenSSL since version
1.1.1.  Unfortunately, that support is limited, as it requires calling
EVP_DigestFinalXOF().  However, the grasshopper code wasn't compatible.

This changeset adds XOF support in grasshopper

This changeset removes the _meth_ calls from test_grasshopper.c (they
should never have been there, but considering support for XOF came so
late in OpenSSL, their presence is understandable) and uses supported
functionality for this sort of thing instead.
