Fix building libstd on on emscripten targets. Squashed 10 commits: 1) The main cause of the problem is that libstd/os/mod.rs treats emscripten targets as an alias of linux targets, whereas liblibc treats emscripten targets as musl-compliant, so it gets a slightly different struct stat64 defined. This commit adds conditional compilation checks to use the correct timestamp format on fs metadata functions in the case of compiling to emscripten targets. 2) Update previous commit to comply with rust formatting standards. Removed tab characters, remove trailing whitespaces. 3) Move emscripten changes into their own file under libstd/os/emscripten Put libstd/os/linux/fs back to the way it was. 4) Cannot use stat.st_ctim on emscripten to get created time. 5) Remove compile-time conditionals for target_env = musl, it looks like musl builds compile fine already. 6) Undone some formatting changes that are no longer needed, Removed some more target_env="musl" compilation checks that I missed from my previous commit. 7) upgrade to liblibc e19309c, it fixes the differences in the musl stat and stat64 definitions. 8) Undo the compile-time checks to check for emscripten (or musl targets) in the FileAttr struct. No longer needed after updating liblibc to e19309c. 9) Change the MetadataExt implementation of emscripten fs.rs module to match the changes in new liblibc. 10) remove a stray return statement, should have been removed in the previous commit. 2016-03-01 20:48:03 +10:00			`//!

Format libstd/os with rustfmt This commit applies rustfmt with rust-lang/rust's default settings to files in src/libstd/os that are not involved in any currently open PR to minimize merge conflicts. THe list of files involved in open PRs was determined by querying GitHub's GraphQL API with this script: https://gist.github.com/dtolnay/aa9c34993dc051a4f344d1b10e4487e8 With the list of files from the script in outstanding_files, the relevant commands were: $ find src/libstd/os -name '*.rs' \ \| xargs rustfmt --edition=2018 --unstable-features --skip-children $ rg libstd/os outstanding_files \| xargs git checkout -- Repeating this process several months apart should get us coverage of most of the rest of the files. To confirm no funny business: $ git checkout $THIS_COMMIT^ $ git show --pretty= --name-only $THIS_COMMIT \ \| xargs rustfmt --edition=2018 --unstable-features --skip-children $ git diff $THIS_COMMIT # there should be no difference 2019-11-27 10:28:21 -08:00			`pub mod raw;`
