linelogcli: a simple CLI tool for linelog
Summary:
The `linelogcli` tool exposes linelog APIs to command line:
- `linelogcli file init`: create a linelog file
- `linelogcli file annotate rev`: run annotate
- `linelogcli file replacelines rev a1:a2 b1:b2`: replace lines
- `linelogcli file info`: show maxrev and buffer size
- `linelogcli file dump`: dump human-readable instructions
It's designed for (fuzz) testing, memory leak checking. It's also
a basic tool for developers to investigate a linelog file.
It's not designed for end users and we will have a separate Python wrapper
implemented in Cython for mercurial integration. Therefore reviewers are
recommended to be less strict for this implementation.
Test Plan:
`make` and test some basic operations:
```
$ ./linelogcli /tmp/foo init annotate 0 replacelines 1 0:0 0:4 annotate - replacelines 2 1:2 10:13 annotate - replacelines 3 2:6 20:22 annotate - replacelines 4 0:4 30:31 annotate - annotate 2 info dump

Also run with `valgrind --tool=memcheck --leak-check=yes` to make sure there is no memory leak.
