Utilize set_surrounding_text request when the text is long

This CL lets SetSurroundingText handle the text longer than 4000 bytes.

zwp_text_input_v1.set_surrounding_text request in wayland protocol only
allows the text shorter than 4000 bytes, so currently we don't send
request when the text is longer than the limitation.
By this change, we send the request for the text longer than 4000 byets
by truncating the text into 4000 bytes unless the selection range is
longer than the limitation.

This change doesn't affect the performance for the text shorter than the
limitation.

Logo Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.

The project's web site is https://www.chromium.org.

To check out the source code locally, don't use git clone! Instead, follow the instructions on how to get the code.

Documentation in the source is rooted in docs/README.md.

Learn how to Get Around the Chromium Source Code Directory Structure .

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.
