Joe Tsai	c2a551469c	taildrop: implement asynchronous file deletion (#9844) ... File resumption requires keeping partial files around for some time, but we must still eventually delete them if never resumed. Thus, we implement asynchronous file deletion, which could spawn a background goroutine to delete the files. We also use the same mechanism for deleting files on Windows, where a file can't be deleted if there is still an open file handle. We can enqueue those with the asynchronous file deleter as well.

Joe Tsai	b1867eb23f	taildrop: add logic for resuming partial files (#9785) ... We add the following API: * type FileChecksums * type Checksum * func Manager.PartialFiles * func Manager.HashPartialFile * func ResumeReader The Manager methods provide the ability to query for partial files and retrieve a list of checksums for a given partial file. The ResumeReader function is a helper that wraps an io.Reader to discard content that is identical locally and remotely. The FileChecksums type represents the checksums of a file and is safe to JSON marshal and send over the wire.

Joe Tsai	37c646d9d3	taildrop: improve the functionality and reliability of put (#9762) ... Changes made: * Move all HTTP related functionality from taildrop to ipnlocal. * Add two arguments to taildrop.Manager.PutFile to specify an opaque client ID and a resume offset (both unused for now). * Cleanup the logic of taildrop.Manager.PutFile to be easier to follow. * Implement file conflict handling where duplicate files are renamed (e.g., "IMG_1234.jpg" -> "IMG_1234 (2).jpg"). * Implement file de-duplication where "renaming" a partial file simply deletes it if it already exists with the same contents. * Detect conflicting active puts where a second concurrent put results in an error.
