Add fuzzing support for some libpurple features

Testing Done:
Hi!

I built and tested all of these fuzzers for libpurple.

You can build them by first building pidgin/libpurple with `--enable-fuzzing` then going into `libpurple/tests` and run `make check`. After that you can run these fuzzers. With a dictionary if you want :)

for example:
```bash
$ ./fuzz_markup_strip_html -dict=dictionaries/html.dict
Dictionary: 465 entries
INFO: Seed: 2274862685
INFO: Loaded 1 modules (3 inline 8-bit counters): 3 [0x5a4ec0, 0x5a4ec3),
INFO: Loaded 1 PC tables (3 PCs): 3 [0x568ee8,0x568f18),
INFO: -max_len is not provided; libFuzzer will not generate inputs larger than 4096 bytes
INFO: A corpus is not provided, starting from an empty corpus

```
