[jbig2dec] Custom allocator now supports test case being run more than once. (#5304) 
To make that possible these things were also done:

 * Rename variables for clarity.
 * Rename functions to separate them from jbig2dec's own allocator API.
 * Consistently use size_t for all memory statistics.
 * Add helper function for checking peak memory use.
 * Add helper function for when limit is reached.
 * Add helper function for when allocations fail.
 * Add helper function for memory statis at end of run (including leak check).

This will help with fixing jbig2dec issue 21675 reported by OSS-fuzz.

OSS-Fuzz: Continuous Fuzzing for Open Source Software

Fuzz testing is a well-known technique for uncovering programming errors in software. Many of these detectable errors, like buffer overflow, can have serious security implications. Google has found thousands of security vulnerabilities and stability bugs by deploying guided in-process fuzzing of Chrome components, and we now want to share that service with the open source community.

In cooperation with the Core Infrastructure Initiative and the OpenSSF, OSS-Fuzz aims to make common open source software more secure and stable by combining modern fuzzing techniques with scalable, distributed execution.

We support the libFuzzer, AFL++, and Honggfuzz fuzzing engines in combination with Sanitizers, as well as ClusterFuzz, a distributed fuzzer execution environment and reporting tool.

Currently, OSS-Fuzz supports C/C++, Rust, Go and Python code. Other languages supported by LLVM may work too. OSS-Fuzz supports fuzzing x86_64 and i386 builds.
