Notes :
* updated _libssh2_get_bignum_bytes and _libssh2_get_string. Now pass in length as an argument instead of returning it to keep signedness correct. Now returns -1 for failure, 0 for success.
_libssh2_check_length now returns 0 on success and -1 on failure to match the other string_buf functions. Added comment to _libssh2_check_length.

OpenSSH Key and ED25519 support #39
Added _libssh2_explicit_zero() to explicitly zero sensitive data in memory #120
* ED25519 Key file support - Requires OpenSSL 1.1.1 or later
* OpenSSH Key format reading support - Supports RSA/DSA/ECDSA/ED25519 types
* New string buffer reading functions - These add build-in bounds checking and convenance methods. Used for OpenSSL PEM file reading.
* Added new tests for OpenSSH formatted Keys
Use checksrc.pl from the curl project, with (for now)
suppressed long line warnings and indentation set to
4 spaces. Fixes are whitespace for the most part.
Warning count went down from 2704 to 12.
Also fix codespell typos, two non-ANSI C89 comments
and a stray tab in include/libssh2.h.

Since they use our own PEM parser which did not support encrypted
PEM files, trying to use such files on these backends failed.
Fix that by augmenting the PEM parser to support encrypted PEM files.
the recent commits converted the tabs to 4 spaces, which matched the
initial indent size. Other commits converted the tabs to 8 spaces, this
didn't match.
All the code has been converted to 4 space indents. No changes to line
lengths or actual code was performed. This is in preperation to my up
coming non-blocking work so my commits should only be code changes and
line lengths in the code I am working on.
