- update to 2.7.8:
* updating code and man page about the way to solve the conflict of
sequentially reading the archive of reference when binary delta is
implicitly present for differential/incremental backups
* added -avc option to surface libcurl verbose messages
* fixed bug in dar where a sanity check about slice min digit detection
was applied to the local filesystem when the backup was stored
remotely, this prevented the reading or remote backups
* exposing libcurl version to the version output (new API call added
* remove extra slash (/) found after hostname in URL passed to libcurl
* fixed self test reported error about mycurl_easyhandle_node.cpp
* improved error message when libcurl fails to connect to an sftp server
* fixed bug in libdar in the way libcurl is called for reading a file
using ftp protocol
* fixed bug in libdar when asking libcurl the size of the file we are
writing (libcurl segfaults with ftp protocol). In addition, we now
record this info during the write process (faster and more efficient).
* fixed bug met when creating a backup on very close and/or high
bandwidth ftp and sftp repos with the --hash option set, triggering a
race condition that led dar to sometime hang unexpectedly.
