Remove the --false-start flag completely. In the Chrome version it has
no affect, and in the Firefox version it may cause connection errors.
This flag doesn't seem to affect TLS or HTTP signatures so is safe to
remove.
The flag seems to cause connection errors with some
http/2 servers. The server chooses http/2 based on alpn but curl
initiates a http/1.1 connection instead. This is an upstream bug in curl
that affects us as well.
Rename the binary files of curl-impersonate so that the Firefox and
Chrome versions can co-exist on the same system. The Firefox version is
now named 'curl-impersonate-ff' and 'libcurl-impersonate-ff' and the
Chrome version is named 'curl-impersonate-chrome' and
'libcurl-impersonate-chrome'. The wrapper scripts look for these names
as well. Symbolic names with the old names are still created inside the
Docker images to keep compatibility as much as possible.
In preparation for merging the support for Chrome impersonation, move
all build files to the 'firefox' folder. The two builds will live
separately as they are rather different (using two different SSL
libraries for instance).
