621080d7c6 Fix compilation issue weh self test defined
1. Surround the generate keys with
`#if ! defined(MBEDTLS_CMAC_ALT) || defined(MBEDTLS_SELF_TEST)`
to resolve build issue when `MBEDTLS_SELF_TEST` is defined for
alternative CMAC as well
2. Update ChangeLog

8873bcc4de Timing self test: increased duration
Increase the duration of the self test, otherwise it tends to fail on
a busy machine even with the recently upped tolerance. But run the
loop only once, it's enough for a simple smoke test.

8064bf3adf New timing unit tests
New set of unit tests for the timing module, instead of just running
the selftest function.

The selftest function sometimes fails on a heavily loaded
machine (such as a typical continuous integration system). Because of
the all-in-one nature of the test and because the exact load pattern
can be hard to reproduce, it is difficult to diagnose failures of CI
runs with selftest. The new tests are more separated and I strove to
point out potential failure modes in comments.

* mbedtls_timing_hardclock: not tested. This function gives so few
  guarantees that there isn't much to test, and it is hard to test
  reliably because clock cycles don't easily relate to time in any
  remotely portable way. This function isn't used in the library
  anyway, it's only there for benchmark programs.
* mbedtls_timing_get_timer: tested by setting a timer and verifying
  that it reaches its target, and by verifying that a timer started
  later than another always has a smaller elapsed time.
* mbedtls_set_alarm: tested by setting an alarm, busy-waiting for it
  and measuring the elapsed time with a timer.
* mbedtls_timing_set_delay, mbedtls_timing_get_delay: tested by
  setting a delay object and watching it go through its two delay
  values, using a timer to check that the delays are passed at the
  expected time.

The tests pass under light to moderate load, but some of them can be
defeated with sufficiently heavy load. This is unavoidable since the
test process to be effectively suspended for any length of time,
making us think that a timer has gone on for too long.

d92f0aa3be mbedtls_timing_get_timer: don't use uninitialized memory
mbedtls_timing_get_timer with reset=1 is called both to initialize a
timer object and to reset an already-initialized object. In an
initial call, the content of the data structure is indeterminate, so
the code should not read from it. This could crash if signed overflows
trap, for example.

As a consequence, on reset, we can't return the previously elapsed
time as was previously done on Windows. Return 0 as was done on Unix.

a0af95f052 Timing: fix mbedtls_set_alarm(0) on Unix/POSIX
The POSIX/Unix implementation of mbedtls_set_alarm did not set the
mbedtls_timing_alarmed flag when called with 0, which was inconsistent
with what the documentation implied and with the Windows behavior.

As noted in #557, several functions use 'index' resp. 'time'
as parameter names in their declaration and/or definition, causing name
conflicts with the functions in the C standard library of the same
name some compilers warn about.

This commit renames the arguments accordingly.
