Currently we use a predefined array to set the
block info output formats, it's fixed and inflexible.
This patch adds two parameters "block_hpps" and "nr_hpps"
in block_info__create_report and other static functions,
in order to let user decide which columns to report and
with specified report ordering. It should be more flexible.
Buffers will be allocated to contain the new fmts, of course,
we need to release them before perf exits.
v3:
---
No change.
v2:
---
New patch created in v2.

It would be nice to print the block percents with colors.
This patch supports the 'Sampled Cycles%' and 'Avg Cycles%'
printed in colors.
For example,
perf record -b ...
perf report --total-cycles or perf report --total-cycles --stdio
percent > 5%, colored in red
percent > 0.5%, colored in green
percent < 0.5%, default color

No change
