infof: remove newline from format strings, always append it
- the data needs to be "line-based" anyway since it's also passed to the
  debug callback/application

- it makes infof() work like failf() and consistency is good

- there's an assert that triggers on newlines in the format string

- Also removes a few instances of "..."

- Removes the code that would append "..." to the end of the data *iff*
  it was truncated in infof()

curl_url_set: reject spaces in URLs w/o CURLU_ALLOW_SPACE
They were never officially allowed and slipped in only due to sloppy
parsing. Spaces (ascii 32) should be correctly encoded (to %20) before
being part of a URL.

The new flag bit CURLU_ALLOW_SPACE when a full URL is set, makes libcurl
allow spaces.

Updated test 1560 to verify.

data_pending: check only SECONDARY socket for FTP(S) transfers
Check the FIRST for all other protocols.

This fixes a timeout in an ftps download. The server sends a TLS
close_notify message in the same packet as the file data. The
close_notify seems to not be handled in the schannel_recv function, so
libcurl is not aware that the server has closed the connection. Thus
libcurl ends up waiting for action on the socket until a timeout is
reached. With the secondary socket check added to the data_pending
function, the close_notify is properly handled, and the ftps transfer
terminates as expected.

http: use credentials from transfer, not connection
HTTP auth "accidentally" worked before this cleanup since the code would
always overwrite the connection credentials with the credentials from
the most recent transfer and since HTTP auth is typically done first
thing, this has not been an issue. It was still wrong and subject to
possible race conditions or future breakage if the sequence of functions
would change.

The data.set.str[] strings MUST remain unmodified exactly as set by the
user, and the credentials to use internally are instead set/updated in
state.aptr.*

Added test 675 to verify different credentials used in two requests done
over a reused HTTP connection, which previously behaved wrongly.

lib: pass in 'struct Curl_easy *' to most functions
... in most cases instead of 'struct connectdata *' but in some cases in
addition to.

- We mostly operate on transfers and not connections.

- We need the transfer handle to log, store data and more. Everything in
  libcurl is driven by a transfer (the CURL * in the public API).

- This work clarifies and separates the transfers from the connections
  better.

- We should avoid "conn->data". Since individual connections can be used
  by many transfers when multiplexing, making sure that conn->data
  points to the current and correct transfer at all times is difficult
  and has been notoriously error-prone over the years. The goal is to
  ultimately remove the conn->data pointer for this reason.

Jay Satiro c0e139a60d transfer: Switch PUT to GET/HEAD on 303 redirect
Prior to this change if there was a 303 reply to a PUT request then
the subsequent request to respond to that redirect would also be a PUT.
It was determined that was most likely incorrect based on the language
of the RFCs. Basically 303 means "see other" resource, which implies it
is most likely not the same resource, therefore we should not try to PUT
to that different resource.

Refer to the discussions in #5237 and #5248 for more information.
