When installing plugins, there is a missing check
for slash (/) in the path on Windows. Note that on
Windows, both / and \ can be used to separate
directories.
This patch fixes the issue by:
- Adding a FN_DIRSEP symbol for all platforms
consisting of a string of legal directory
separators.
- Adding a charset-aware version of strcspn().
- Adding a check_valid_path() function that uses
my_strcspn() to check if any FN_DIRSEP character
is in the supplied string.
- Using the check_valid_path() function in
sql_plugin.cc and sql_udf.cc (which means
replacing the existing test there).

The problem was that UNINSTALL PLUGIN wasn't performing privilege
checks before removing a plugin. Any user (including users without
any kind of privileges) could uninstall any plugin.
The solution is to verify if the user has the DELETE privilege for
the mysql.plugin table before uninstalling a plugin.
mysql-test/r/plugin_not_embedded.result:
Add test case result for Bug#51770.
mysql-test/t/plugin_not_embedded-master.opt:
Add example plugin path.
mysql-test/t/plugin_not_embedded.test:
Add test case for Bug#51770.
Skip embedded as test relies on privileges checks.
