libssh2: keep sftp errors as 'unsigned long'

2020-06-08T06:38:48+00:00

Remove weird work-around for storing the SFTP errors as int instead of
the "unsigned long" that libssh2 actually returns for SFTP errors.

Closes #5534

timeouts: change millisecond timeouts to timediff_t from time_t

2020-05-30T21:10:57+00:00

For millisecond timers we like timediff_t better. Also, time_t can be
unsigned so returning a negative value doesn't work then.

Closes #5479

libssh2: convert over to use dynbuf

2020-05-05T12:54:07+00:00

In my very basic test that lists sftp://127.0.0.1/tmp/, this patched
code makes 161 allocations compared to 194 in git master. A 17%
reduction.

Closes #5336

libssh2: set the expected total size in SCP upload init

2020-05-02T14:38:48+00:00

... as otherwise the progress callback gets called without that
information, making the progress meter have less info.

libssh: avoid options override by configuration files

2020-04-24T22:53:11+00:00

Previously, options set explicitly through command line options could be
overridden by the configuration files parsed automatically when
ssh_connect() was called.

By calling ssh_options_parse_config() explicitly, the configuration
files are parsed before setting the options, avoiding the options
override.  Once the configuration files are parsed, the automatic
configuration parsing is not executed.

2020-04-17T21:22:26+00:00

From libssh 0.9.0, ssh_key_type() returns different key types for ECDSA
keys depending on the curve.
