Dave Watson f459d5a203 Detect failed profile fetches 
Summary:

Currently an HTTP error response will still try to be parsed, resulting in these messages:

substr outside of string at /home/davejwatson/local/jemalloc-github/bin/jeprof line 3635, <PROFILE> line 1.
Use of uninitialized value in string eq at /home/davejwatson/local/jemalloc-github/bin/jeprof line 3635, <PROFILE> line 1.
substr outside of string at /home/davejwatson/local/jemalloc-github/bin/jeprof line 3637, <PROFILE> line 1.
Use of uninitialized value in string eq at /home/davejwatson/local/jemalloc-github/bin/jeprof line 3637, <PROFILE> line 1.
/home/davejwatson/jeprof/server.1452638936.localhost.pprof.heap: header size >= 2**16

After this fix, curl will return an error status code that will be correctly checked at line 3536, resulting in this error message:

Failed to get profile: curl -s --fail 'http://localhost:4010/pprof/heap' > /home/davejwatson/jeprof/.tmp.server.1452639085.localhost.pprof.heap: No such file or directory

Test Plan:

Tested with MALLOC_CONF="prof:false".  Also tested fetching symbols.  Didn't test redirects, but this should only affect http error codes >= 400

README 

jemalloc is a general purpose malloc(3) implementation that emphasizes
fragmentation avoidance and scalable concurrency support.  jemalloc first came
into use as the FreeBSD libc allocator in 2005, and since then it has found its
way into numerous applications that rely on its predictable behavior.  In 2010
jemalloc development efforts broadened to include developer support features
such as heap profiling, Valgrind integration, and extensive monitoring/tuning
hooks.  Modern jemalloc releases continue to be integrated back into FreeBSD,
and therefore versatility remains critical.  Ongoing development efforts trend
toward making jemalloc among the best allocators for a broad range of demanding
applications, and eliminating/mitigating weaknesses that have practical
repercussions for real world applications.

The COPYING file contains copyright and licensing information.

The INSTALL file contains information on how to configure, build, and install
jemalloc.

The ChangeLog file contains a brief summary of changes for each release.
