bf416e7daf auto merge of #9713 : sfackler/rust/dynamic_lib, r=alexcrichton
The root issue is that dlerror isn't reentrant or even thread safe.

The solution implemented here is to make a yielding spin lock over an
AtomicFlag. This is pretty hacky, but the best we can do at this point.
As far as I can tell, it isn't possible to create a global mutex without
having to initialize it in a single threaded context.

The Windows code isn't affected since errno is thread-local on Windows
and it's running in an atomically block to ensure there isn't a green
thread context switch.

Closes #8156

2733b189ac auto merge of #9250 : erickt/rust/num, r=erickt
This PR solves one of the pain points with c-style enums. Simplifies writing a fn to convert from an int/uint to an enum. It does this through a `#[deriving(FromPrimitive)]` syntax extension.

Before this is committed though, we need to discuss if `ToPrimitive`/`FromPrimitive` has the right design (cc #4819). I've changed all the `.to_int()` and `from_int()` style functions to return `Option<int>` so we can handle partial functions. For this PR though only enums and `extra::num::bigint::*` take advantage of returning None for unrepresentable values. In the long run it'd be better if `i64.to_i8()` returned `None` if the value was too large, but I'll save this for a future PR.

Closes #3868.

5a1073fbab auto merge of #9722 : alexcrichton/rust/less-mem, r=sanxiyn
According to http://huonw.github.io/isrustfastyet/mem/#012f909, the "const
marking" pass generates about 400MB of extra memory during compilation. It
appears that this is due to two different factors:

    1. There is a `ccache` map in the ty::ctxt which is only ever used in this
       pass, so this commit moves the map out of the ty::ctxt struct and into
       just this pass's visitor. This turned out to not benefit that much in
       memory (as indicated by http://i.imgur.com/Eo4iOzK.png), but it's helpful
       to do nonetheless.

    2. During const_eval, there are a lot of lookups into decoding inlined items
       from external crates. There is no caching involved here, so the same
       static or variant could be re-translated many times. After adding
       separate caches for variants and statics, the memory peak of compiling
       rustc decreased by 200MB (as evident by http://i.imgur.com/ULAUMtq.png)

The culmination of this is basically a slight reorganization of a caching map
for the const_eval pass along with a 200MB decrease in peak memory usage when
compiling librustc.

Currently these include `libgcc_s_dw2-1.dll`, `libstdc++-6.dll` and `libpthread-2.dll`.   Note that the latter will need to be changed to `pthreadGC2.dll` once Windows build bots get upgraded to mingw 4.0

This PR removes these specific "obsolete syntax"/"suggestion for change" errors and just lets the parser run into regular parser errors for long-invalid syntax. I also removed `ObsoletePrivSection` which apparently dates further back than cmr or I could recall and `ObsoleteUnenforcedBound` which seemed unused. Also I removed `ObsoleteNewtypeEnum`.

Replaces existing tests for removed obsolete-syntax errors with tests
for the resulting regular errors, adds a test for each of the removed
parser errors to make sure that obsolete forms don't start working
again, removes some obsolete/superfluous tests that were now failing.

Deletes some amount of dead code in the parser, also includes some small
changes to parser error messages to accomodate new tests.

do_strptime() and do_strftime()

I don't see any reason why src/libextra/time.rs has two functions that just call a very similar function, which only use is to be called by them.
strftime() just calls do_strftime()
strptime() just calls do_strptime()
and the do_functions aren't called by anyone else.
the parameters and return types are exactly the same in both levels, so I just have removed the second layer.

Unless there is a need for that second level.

88593fc3fc Document logging and remove old functions
This adds a large doc-block to the top of the std::logging module explaining how
to use it. This is mostly just making sure that all the information in the
manual's section about logging is also here (in case someone decides to look
into this module first).

This also removes the old console_{on,off} methods. As far as I can tell, the
functions were only used by the compiler, and there's no reason for them to be
used because they're all turned off by default anyway (maybe they were turned on
by default at some point...)

I believe that this is the final nail in the coffin and closes #5021
