CertificateContent and PrivateKeyContent now have two valid formats:
It can be in format PEM (multiple lines) or a single line base64 encoded
PEM.
The first format is preferrable in case the pf_config* API is used to
set the certificate/key, the latter in case an actual config file is in
use where multiline configuration data can not be directly entered.
The decoded base64 data might contain PEM with/without/with multiple
'\0' at the end of the string. We do not want to drag this through our
code so ensure the length matches the string length including '\0'
This adds a User, Domain and Password parameter in the Target section of the configuration
to specify and use a fixed backend user, domain or password (overriding the one
passed by the front user).
The rework introduce a stateful dynamic channel treatment, so that we can take early decisions
for data packet (dropping all the current packet or pass it), but also reassemble important
packets like channel creation.
* Split out proxy headers and moved to public API to allow external
modules to be built.
* Split proxy into proxy library and proxy binary. The library
can be used by other applications and provides a simple API
* Improved channel passthrough, now all channels including dynamic
channels work.
* Extended module API to hook more events, improved module samples
* Cleaned up proxy code, removed global static variables used,
added WINPR_ASSERT
* Add support for C++ plugins.
* Seperate between a "module" and a "plugin": a module is a shared
library that exposes a function called "proxy_module_entry_point". This
function gets a parameter to `proxyPluginsManager*`, which can be used to
register plugins.
* Refine the API of the modules infrastructure:
* use proxyData* instead of rdpContext* when firing a hook or calling a filter.
* use clearer names.
* Instead of having to specify a path for each module to be loaded in
the configuration, the proxy now loads modules from specificed
directory, using the CMAKE variable PROXY_PLUGINDIR.
* Add an option to specify required plugins: plugins that the proxy
wouldn't start without having them fully loaded.
