[infer][PR] Clean temporary files created by the clang frontend Summary: This commit augments codes to clean up temporary files generated by the clang frontend. Currently clang frontend leaves large number of temporary files int the tmp directory, and it could be seen for example by running these command: ``` git clean -xdf infer/models/ mkdir /tmp/infer env TMPDIR=/tmp/infer make infer_models ls -l /tmp/infer ``` P.S. Analyzing real project could easily cause each infer capture to leave hundreds of files in /tmp P.P.S. There are 11 total references to Filename.temp_file however, other 9 seems don't leak temporary files in such large scale (at least not when using the clang frontend).

[cleanup] add missing `open! IStd` Summary: Almost all the files are supposed to do this. When they don't, the build adds it automatically anyway, but it's better to always include it to avoid confusion (and help other automated tools).

[taskbar] it is born Summary: Replace the previous outputting of "." and "F" with an actual progress bar and a multiline display of what procedure each process is currently busy analysing. Observe: ```lang=text Found 19 source files to analyze in /home/jul/code/openssl-1.1.0d/infer-out 7/19 [######################......................................] 36% ⊢ [ 1.14s] crypto/mem.c: CRYPTO_malloc ⊢ [ 1.68s] crypto/o_time.c: julian_adj ⊢ [ 0.50s] crypto/mem.c: CRYPTO_zalloc ⊢ [ 1.80s] crypto/o_str.c: OPENSSL_strlcpy ``` This works by setting up a worker pool (as before) that waits to receive jobs (not as before: we used to fork for each new job). Unix pipes are used for communication. The new worker pool can be used to experiment with other concurrency models, such as reviving per-procedure-parallelism, or making sure each procedure is analysed only once. Perf tests indicate that this version is no slower than the previous one, either on laptops or devserver: about 3% worse user time but ~40% better system time. This new version forks <jobs> processes whereas the previous version would fork `O(number of source files)` times. `infer -j 1` shows a progress bar that doesn't update timing info (because it would need a second process to do that).
