CURL_IGNORE_DEPRECATION

Hackers,

I just noticed that we have some ad-hoc hacks for the
CURL_IGNORE_DEPRECATION macro in the pgindent Perl script, which I find
a bit uncomfortable. Given that we use that macro in a single place,
what do you think about removing that and making a more surgical
intervention to fix pgindent problem with it? I propose the attached.

For context: in curl, that macro is defined like this

#define CURL_IGNORE_DEPRECATION(statements) \
_Pragma("GCC diagnostic push") \
_Pragma("GCC diagnostic ignored \"-Wdeprecated-declarations\"") \
statements \
_Pragma("GCC diagnostic pop")

(with #ifdef guards and whatnot). Because it has a _Pragma after the
statements argument, any uses of this macro must have a terminating
semicolon, which pgindent does not like. (It's also IMO rather
C-unlike). So my approach here is to add another macro to insert that
semicolon where it's needed. Of course, there's nothing we can do with
CURL_IGNORE_DEPRECATION() itself, given that it's upstream from us.

Thoughts?
