Refactor abort signal handling 
- Print signal name to term
- Add -rdynamic option to generate Linux symbol names in backtrace
- Raise default signal after handler to ensure program termination

Print a stack trace on unexpected term signal (e.g. SIGABRT) 
For OSX and Linux, add a signal handler to SIGABRT, SGIFPE, SIGILL,
SIGSEGV, and SIGBUS. When the program terminates unexpectedly the
handler will print the current stack to the terminal to help determine
the location of the failure.

On OSX the output will look like:

```
Stack trace:
4   zstd                                0x000000010927ed96 main + 16886
5   libdyld.dylib                       0x00007fff767d1015 start + 1
6   ???                                 0x0000000000000001 0x0 + 1
```

On Linux the output will look like:

```
Stack trace:
./zstd() [0x4b8e1b]
./zstd() [0x4b928a]
./zstd() [0x403dc2]
/lib64/libc.so.6(__libc_start_main+0xf5) [0x7f5e0fbb0445]
./zstd() [0x405754]
```

As is, the code does not function on WIN32.

[zstd] Fix seqStore growth
 2018-08-28 17:10:25 -07:00

0c66a44d1b first working test program 
measures :
- compression ratio with / without dictionary
- create one dictionary per block
- memory budget for dictionaries
- decompression speed, using one different dictionary per block

current limitations :
- only one file
- 4K blocks only
- automatic dictionary built with 4K size

dictionary can be selected on command line, with -D

5e580de6da [zstd] Fix seqStore growth 
We could undersize the literals buffer by up to 11 bytes,
due to a combination of 2 bugs:
* The literals buffer didn't have `WILDCOPY_OVERLENGTH` extra
  space, like it is supposed to.
* We didn't check the literals buffer size in `ZSTD_sufficientBuff()`.

0071e8348f restored assert() in paramgrill 
assert() in paramgrill are not in the benchmark path.
They should remain active, as they don't impact measurements, and their runtime is insignificant.
