* Resolve 'Unexpected end of input when converting from type string to type ulong' due to handleLocalFileTrigger() being triggered post a directory creation event and scanning the entire path for new data taking precedence.
* Remove CurlOption.ssl_verifypeer configuration which was added when developing the multi-threaded transfer handling and OpenSSL was causing issues due to insufficient file handles to open the read of the CA Certificate. If the SSL CA Certificate cannot be read, we should hard exit.
* Check the system for any session files, that indicate that a session upload did not complete
* Change from using a CRC32 of the file, to a random 16 character alphanumeric string to use as the session filename extension as it is not computationally valid to do a CRC32 on large files
* When enabling system logging to a log file, the actual ERROR line is forced to a new line in the application log. The reason for this is the \n prefix in the error message, which was in place so that when performing CLI logging or systemd logging, the error message would be displayed clearly. This change removes the \n from the actual error message, but inserts a newline before the error message is displayed (and also in some cases post error message) - thus keeping the application runtime look and feel, but improving the application log output.
* When the client needs to exit due to an issue, ensure that the curl http instance is shutdown before the exit is performed. This also potentially solves some segmentation faults seen on Ubuntu|Debian platforms due to issues in the shared library libphobos2-ldc-shared.so.X
* contrib: remove bash hashbang from completion
This file starts with the #! sequence that marks interpreted scripts, but
it is a bash completion script that is merely intended to be sourced.
* src: spelling error (Attemtping => Attempting)
* src: spelling error (reponse => response)
* src: spelling error (sucessfully => successfully)
* Implement a check to validate local filesystem available space before attempting file download
* Implement 'space_reservation' config option with a default value of 50 MB
* Prevent the original run-away logging error message 'Failed initialization on handle XXXX' from occurring if the system is out of space
* Update documentation and man page
* Explicitly set libcurl options to ignore SIGPIPE, use TCP NAGLE and ensure we are re-using connections. These should be 'enabled by default' by libcurl, but we need to ensure we are setting them to their supposed default
Potentially resolves the following issues: #494, #753, #792, #884, #1162, #1408, #1520, #1526 + others.
* This change is to create an argument version of the config operation_timeout.
There are many times where one may need to temporarily increase the timeout for an operation of a single large file that takes longer than the configured timeout. The command line argument is an excellent way to override the default or 'config' set option if required.
* Catch a Invalid UTF-8 handling error when attempting to initialise the application. This is caused by the 'path' to the application configuration (typically ~/.config/onedrive) contains a bad UTF-8 character thus cannot be read / initialised
* When syncing OneDrive Business Shared Folders and using --single-directory, select correct driveId and itemId for the remote directory that needs to be synced
* Normally, the 'remoteItem' field will contain 'fileSystemInfo' however, if the user uses the 'Add Shortcut ..' option in OneDrive WebUI to create a 'link', this object, whilst remote, does not have 'fileSystemInfo' in the expected place, this leading to a application crash
* Use 'nextLink' value if present when searching for specific SharePoint site names
* Update error output to provide more details why an error occurred if a SharePoint site lacks the details we need to perform the match
