This commit decreases 15 shift/reduce conflicts.
The location of this error recovery is ambiguous.
For example, there are two ways to interpret the following code:
1 config FOO
2 bool "foo"
[A] Both lines are reduced together into a config_stmt.
[B] The only line 1 is reduced into a config_stmt, and the line 2
matches to "option_name error T_EOL"
Of course, we expect [A], but [B] could be grammatically possible.
Kconfig has no terminator for a config block. So, we cannot detect its
end until we see a non-property keyword. People often insert a blank
line between two config blocks, but it is just a coding convention.
Blank lines are actually allowed anywhere in Kconfig files.
The real error is when a property keyword appears right after "endif",
"endchoice", "endmenu", "source", "comment", or variable assignment.
Instead of fixing the grammatical ambiguity, I chose to simply remove
this error recovery.
The difference is
unexpected option "bool"
... is turned into a more generic message:
invalid statement
