[ftfuzzer] Restrict number of tested bitmap strikes.
Malformed fonts often have large values for the number of bitmap
strikes, and FreeType doesn't check the validity of all bitmap
strikes in advance.
Reported as
https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=353
* src/tools/ftfuzzer/ftfuzzer.cc: Include `stdlib.h' for `rand'.
(Random): Small class to provide n randomly selected numbers
(without repitition) out of the value set [0,N].
(LLVMFuzzerTestOneInput): Use it to test only up to 10 bitmap
strikes.

[ftfuzzer] Add support for multiple files (patch #8779).
Currently, libFuzzer only supports mutation of a single file. We
circumvent this problem by using an uncompressed tar archive as
multiple-file input for the fuzzer.
This patch enables tests of `FT_Attach_Stream' and AFM/PFM parsing;
a constructed tarball should contain a font file as the first
element, and files to be attached as further elements.
* src/tools/ftfuzzer/ftfuzzer.cc: Include libarchive headers.
(archive_read_entry_data, parse_data): New functions.
(LLVMFuzzerTestOneInput): Updated.
* src/tools/ftfuzzer/ftmutator.cc: New file, providing a custom
mutator for libFuzzer that can mutate tarballs in a sensible way.
