... since the 'tv' stood for timeval and this function does not return a
timeval struct anymore.
Also, cleaned up the Curl_timediff*() functions to avoid typecasts and
clean up the descriptive comments.

... to cater for systems with unsigned time_t variables.
- Renamed the functions to curlx_timediff and Curl_timediff_us.
- Added overflow protection for both of them in either direction for
both 32 bit and 64 bit time_ts
- Reprefixed the curlx_time functions to use Curl_*

First: this function is only used in debug-builds and not in
release/real builds. It is used to drive tests using the event-based
API.
A pointer to the local struct is passed to CURLMOPT_TIMERDATA, but the
CURLMOPT_TIMERFUNCTION calback can in fact be called even after this
funtion returns, namely when curl_multi_remove_handle() is called.

... to make all libcurl internals able to use the same data types for
the struct members. The timeval struct differs subtly on several
platforms so it makes it cumbersome to use everywhere.

... since the total amount is low this is faster, easier and reduces
memory overhead.
Also, Curl_expire_done() can now mark an expire timeout as done so that
it never times out.
Closes #1472

A) reduces the timeout lists drastically
B) prevents a lot of superfluous loops for timers that expires "in vain"
when it has actually already been extended to fire later on

Safe to silence warning adding time delta of poll, which can trigger on

When receiving chunked encoded data with trailers, and the write
callback returns PAUSE, there might be both body and header to store to
resend on unpause. Previously libcurl returned error for that case.
Added test case 1540 to verify.

Replace use of fixed macro BUFSIZE to define the size of the receive
buffer. Reappropriate CURLOPT_BUFFERSIZE to include enlarging receive
buffer size. Upon setting, resize buffer if larger than the current
default size up to a MAX_BUFSIZE (512KB). This can benefit protocols
like SFTP.

- Call Curl_initinfo on init and duphandle.
Prior to this change the statistical and informational variables were
simply zeroed by calloc on easy init and duphandle. While zero is the
correct default value for almost all info variables, there is one where
it isn't (filetime initializes to -1).

... to make it less likely that we forget that the function actually

Previously, passing a timeout of zero to Curl_expire() was a magic code
for clearing all timeouts for the handle. That is now instead made with
the new Curl_expire_clear() function and thus a 0 timeout is fine to set
and will trigger a timeout ASAP.
This will help removing short delays, in particular notable when doing
HTTP/2.

- Curl_ipv6works() is not thread-safe until after the first call, so
call it once during global init to avoid a possible race condition.

... and save the typedef'ed names for headers and external APIs.

curl_printf.h defines printf to curl_mprintf, etc. This can cause
problems with external headers which may use
__attribute__((format(printf, ...))) markers etc.
To avoid that they cause problems with system includes, we include
curl_printf.h after any system headers. That makes the three last
headers to always be, and we keep them in this order:
curl_printf.h
curl_memory.h
memdebug.h
None of them include system headers, they all do funny #defines.

They tend to never get updated anyway so they're frequently inaccurate
and we never go back to revisit them anyway. We document issues to work

This header file must be included after all header files except
memdebug.h, as it does similar memory function redefinitions and can be
similarly affected by conflicting definitions in system or dependent
library headers.

Coverity detected this. CID 1241954. When Curl_poll() returns a negative value
'mcode' was uninitialized. Pretty harmless since this is debug code only and
would at worst cause an error to _not_ be returned...

As this makes curl_global_init_mem() behave the same way as
curl_global_init() already does in that aspect - the same number of
curl_global_cleanup() calls is then required to again decrease the
counter and then eventually do the cleanup.
