nanosecond: fix up conversion of ticks to nsec by doing the conversion in 2 stages

The ticks to nsec conversion is challenging because we care about small
differences between very large numbers. The solution used here is to do the
conversion in two stages.

The first stage carves out large chunks of time. For this patch each chunk is
approximately an hour long. The number of ticks per hour is calculated. When a
conversion is requested, an hour worth of time is accumulated each time this
number of ticks has elapsed.

The remaining ticks are handled in the second stage with the standard
multiplication and shift conversion.

This strategy deals with the multiplication-and-shift overflow problem by
limiting the scale of this operation to at most one hour. This way we can have
reasonable accuracy with this portion of the conversion. At the same time the
first stage allows the ticks to nsec conversion to be valid for long periods
of time.

filesetup: fix size percentage calculations when using offset

"When an fio job uses a non-zero offset value and a non-zero size
parameter, the working set size on disk is skewed. For a 64k file, the
job provided touches the following blocks:

dd if=/dev/zero of=/tmp/fiofile bs=64k count=1
fio --stonewall --filename=/tmp/fiofile --rw=write \
    --name=firstquarter  --size=25% --offset=0   --buffer_pattern=0x11 \
    --name=secondquarter --size=25% --offset=16k --buffer_pattern=0x22 \
    --name=thirdquarter  --size=25% --offset=32k --buffer_pattern=0x33

|1111111111111111|222222222222----|33333333--------|----------------|
0                16k              32k              48k              64k

1=written by firstquarter, 2=written by secondquarter, 3=written by
thirdquarter

It seems the expected vs. actual math on working set size is
(size_param_percent * size_of_file) vs.
(size_param_percent * (size_of_file - offset))."

Fix this by always calculating the percentage of the full file's size.
Also bound the I/O to be within the existing file's size when using a
size percentage to handle the case where the addition of an offset would
otherwise force I/O to go beyond the existing file size e.g.:

dd if=/dev/zero of=/tmp/fiofile bs=64k count=1
fio --stonewall --filename=/tmp/fiofile --rw=write \
    --name=beyond --size=100% --offset=32k --buffer_pattern=0x11

In the above, we ensure we only do 32k of I/O (rather than the 64k
implied by size=100%).

Drop circular dependency in log.c and lib/output_buffer.c

i.e. log.c is using buf_output_add() in lib/output_buffer.c, while
lib/output_buffer.c is using log_info_buf() in log.c.

This commit removes this dependency from lib/output_buffer.c by
dropping log_info_buf() call from a library function buf_output_flush(),
and then as a result rename buf_output_flush() to buf_output_clear()

independently by __show_run_stats() which was the only caller of
buf_output_flush().

log_info_buf() returning 0 on !len is necessary to keep this commit
without making functional difference. dprint()/log_info() basically
never pass NULL or "" to log_info_buf(), but __show_run_stats() would

This commit gets rid of struct thread_data argument from an inlined

function td_fill_rand_seeds(td). This can simply be called from

configure: Add missing $val != "yes" test to override compile_prog() result

Since it's possible for some platforms to use statically configured
configurations (e.g. see around L350 for Cygwin), it should test if
the variable hasn't been set to "yes" before initializing the variable
with "no", so that compile_prog() result can be safely ignored when
the platform knows it's supported.

ca205a75 (configure: Make Cygwin take regular configure path) started
this due to a major change in the configuration path, which changed
Cygwin to take the normal path taken by all other platforms, and
these two were added after that change.
