* SyncEngine: allow for multiple calls to init by saving the state
* Factor out syncengine initialization code so that it can be reused
* Don't exit in monitor when started offline
* Always call initSyncEngine during regular syncs, this will call the SyncEngine init routine which caches the state, thus a quasi no-op.
* Add forgotten http.shutdown
This change adjusts the two core timeout parameters of libcurl operation
- dataTimeout: changed from 3600sec to 300sec
this timeout controls the max time when there is no data incoming
(actually below CURLOPT_LOW_SPEED_LIMIT)
- operationTimeout: added 3600sec
this timeout controls the maximally allowed connection timeout
* install documentation files into $PREFIX/share/doc/onedrive/
* add man page and install it, ignore generated version

* Change '--download' to '--download-only' to align with '--upload-only'
* Enable logging to a separate file only if the '--enable-logging' flag is passed through at client run time
* Implement configuration option for logfile location, if logging is enabled
* Refactor PR104 for latest code base to enable client use with SharePoint libraries
* Implement '--disable-upload-validation' as SharePoint modifies files when uploaded
* Enable '--disable-upload-validation' by default if account type is documentLibrary - as most likely this is a SharePoint repository
* Remove HTTP 1.1 downgrade for session uploads
* Handle HTTP/2 0 (zero) response code for successful session data upload
* Add debugging for actual server response, not curl interpreted response when using --debug-https
* Update initial Curl 7.62.0 fix with a better solution which handles the redirect's given by HTTP/2 connections (credit @Popa21)
* Use HTTP/1.1 for session uploads otherwise the response when using HTTP/2 generates a 'JSONValue is not an object' error
* Handle HTTP request returned status code 412 (Precondition Failed) for session uploads to OneDrive Personal Accounts
* Fix Failed to remove file /root/.config/onedrive/resume_upload: No such file or directory if there is a session upload error and the resume file does not get created
* Handle response codes when using 2 different systems using --upload-only but the same OneDrive account and uploading the same filename to the same location
* Add a check to validate if the parentReference object has a path object
* Fix spelling error - trough -> through
* Only upload changes on remote folder if the item is in the database - dont assert if false
* Update handling of shared folders and items which was previously broken to a OneDrive API change
* Extract syncFolderName from either local or remote folder - not just local folder.
* Add try & catch in the case of a 504 error being generated to upload the file. Currently, if a 504 is generated, it is handled gracefully, but further files to upload are stopped
* Update where ever there is a 404 try block, add a if statement to capture if a 5xx error is returned as well
