* In case of non-blocking BIO layers the proxy read functions bailed
out with an error. Retry reading in that case unless the
TcpConnectTimeout is exceeded
* Terminate proxy read operations if rdpContext::abortEvent is set
* Properly split certificate_store, certificate_data, certificate and
private key functions to files
* Prefix all functions with freerdp_ to have a unique name
* Update certificate store to use one file per host instead of
known_hosts2
* Merge CryptoCert and rdpCertificate
* Fixed format strings to match arguments
Reviewed and replaced all %d specifiers to match proper type
* Added proxy dynamic channel command type to log messages.
A proxy URI was parsed both in the function `proxy_read_environment()` in
`libfreerdp/core/proxy.c` and in the function
`freerdp_client_settings_parse_command_line_arguments()` in
`client/common/cmdline.c`. But only the latter was taking into account
that the URI can contain a user and password, which made it impossible
to use a proxy with authentication by just using an environment
variable like `https_proxy`.
The function `proxy_parse_uri()` in `libfreerdp/core/proxy.c` was
clearly not parsing the optional username and password.
This commit moves the code from `client/common/cmdline.c` to
`libfreerdp/common/settings.c` into a function `proxy_parse_uri()` so
redundant code is avoided. This function is then called in both
instances where a proxy URI is parsed.
Some minor adjustment were made to the code, so the `WLog_INFO()`
statement at the end works in both cases, where credentials were either
provided or not. Also, some error messages were added or clarified.
If the parsing of the environment variable fails, we ignore it entirely
(with a warning) and proceed.
This patch adds support for authentication when the connection is done
through a HTTP proxy.
It only supports HTTP Basic Authentication (like `curl --proxy`).
It is tested against Apache 2.4.
