rust-chg: update name of the server process
This is a copy of updateprocname() of hgclient.c.
At this point, rust-chg is basically functional. I did dogfooding for
a couple of weeks in 2018. There are a few remaining tasks:
a. loop detection by CHGINTERNALMARK
b. forward unsupported commands (notably serve -d) to real hg
c. better handling of early server exception
d. modernize codebase (2018 edition, impl trait, async/await)
For (d), we'll probably want to switch to async-std, but I'm thinking of
upgrading to Tokio 0.2 as an intermediate step since process API isn't
ported to async-std yet. I'm pretty sure future migration to async-std
will be painless compared to the mass rewrite from futures-0.1 to 0.3.
