Reduce duplicate code by moving screen remapping and validation of the info message into the `AddInfoMsg` function.
Check for valid kill message before creating text containers, so they are not created and deleted unnecessarily.
Assign info message type directly instead of passing it as a separate parameter.
Combine `CreateNamesIfNotCreated` and `CreateFinishTextContainersIfNotCreated` functions to `CreateTextContainersIfNotCreated` function to reduce duplicate code on usage.
Extract duplicate code for determining name color in info messages as lambda function.
For consistency between 0.6 and 0.7 clients, also show kill messages for 0.7 clients, now that DDNet client also supports finish messages.
Closes#5623.
Instead of preventing the client from quitting/restarting while a warning is shown in the menus, add warnings that should be shown after quitting/restarting (i.e. the warning when the config could not be saved) to a separate list and show these warnings using an OS message box after the client has been closed. Otherwise, the client is prevented from closing if a warning is shown without being automatically hidden, which causes the client to hang indefinitely in the CI.
The message boxes for warnings must be shown after the client has already been completely shutdown, otherwise the regular shutdown with the Vulkan backend crashes because showing the message box has already partially deinitialized the backend.
The quitting/restarting client state is now checked after updating the FIFO component, so quitting/restarting initiated via FIFO is effective immediately, although this should have little effect in practice.
For completeness, a log message is added also for the case that the config was saved successfully.
The GitHub CI seems to automatically confirm/disable OS message boxes, so they should not block workflows.
Add assertions to ensure that the HTTP request result data and SHA256 are available when getting them instead of returning `nullptr` and `SHA256_ZEROED` when they are not.
Rename `CHttpRequest::Sha256` function to `ResultSha256`.
Because of incorrect index/size math, two favorite communities were removed when exceeding the maximum number of three favorite communities instead of only one. The check can be simplified because the maximum number of favorite communities can never be exceeded, so at most the first element needs to be removed from the vector.
Closes#7935.
