Other changes include:
* utils: utilsGenerateFormattedSizeString() now takes an input double instead of size_t.
* DownloadTask: calculated speed is now expressed in bytes per second, so now it's up to the caller to convert it to other units.
* DownloadTask: set download size and percentage if the download size isn't known and we're dealing with the final chunk.
* http: slightly improved CURL error info formatting.
* OptionsTab: fully implemented NSWDB XML update option.
Other changes include:
* AsyncTask: use a recursive mutex instead of atomics. Fixes build issues related to non-trivially-copyable elements.
* http: remove CURLOPT_ACCEPT_ENCODING option in httpPerformGetRequest().
Only supports GET requests, but that's more than enough for the time being.
Other changes include:
* OptionsTab: added an option to update the NSWDB XML (not implemented yet).
* config: add missing flag check in getters and setters.
* Move default socket initialization from utils.c to services.c.
