getStandardDynamicLinkerPath renamed and no allocator
* `std.Target.getStandardDynamicLinkerPath` =>
   `std.Target.standardDynamicLinkerPath`
 * it now takes a pointer to fixed size array rather than an allocator
 * `std.zig.system.NativeTargetInfo.detect` now supports reading
   PT_INTERP from /usr/bin/env

separate std.Target and std.zig.CrossTarget
Zig now supports a more fine-grained sense of what is native and what is
not. Some examples:

This is now allowed:
-target native

Different OS but native CPU, default Windows C ABI:
-target native-windows
This could be useful for example when running in Wine.

Different CPU but native OS, native C ABI.
-target x86_64-native -mcpu=skylake

Different C ABI but otherwise native target:
-target native-native-musl
-target native-native-gnu

Lots of breaking changes to related std lib APIs.
Calls to getOs() will need to be changed to getOsTag().
Calls to getArch() will need to be changed to getCpuArch().

Usage of Target.Cross and Target.Native need to be updated to use
CrossTarget API.

`std.build.Builder.standardTargetOptions` is changed to accept its
parameters as a struct with default values. It now has the ability to
specify a whitelist of targets allowed, as well as the default target.
Rather than two different ways of collecting the target, it's now always
a string that is validated, and prints helpful diagnostics for invalid
targets. This feature should now be actually useful, and contributions
welcome to further improve the user experience.

`std.build.LibExeObjStep.setTheTarget` is removed.
`std.build.LibExeObjStep.setTarget` is updated to take a CrossTarget
parameter.

`std.build.LibExeObjStep.setTargetGLibC` is removed. glibc versions are
handled in the CrossTarget API and can be specified with the `-target`
triple.

`std.builtin.Version` gains a `format` method.

update std lib to new Target API 2020-02-28 14:51:54 -05:00

introduce operating system version ranges as part of the target
* re-introduce `std.build.Target` which is distinct from `std.Target`.
   `std.build.Target` wraps `std.Target` so that it can be annotated as
   "the native target" or an explicitly specified target.
 * `std.Target.Os` is moved to `std.Target.Os.Tag`. The former is now a
   struct which has the tag as well as version range information.
 * `std.elf` gains some more ELF header constants.
 * `std.Target.parse` gains the ability to parse operating system
   version ranges as well as glibc version.
 * Added `std.Target.isGnuLibC()`.
 * self-hosted dynamic linker detection and glibc version detection.
   This also adds the improved logic using `/usr/bin/env` rather than
   invoking the system C compiler to find the dynamic linker when zig
   is statically linked. Related: #2084
   Note: this `/usr/bin/env` code is work-in-progress.
 * `-target-glibc` CLI option is removed in favor of the new `-target`
   syntax. Example: `-target x86_64-linux-gnu.2.27`

closes #1907

arm baseline CPU is v7a rather than v6m
v6m is thumb-mode and the baseline should probably be an 'a' variant.

std.time.Timer.lap: only read system time once (#4533)
Calling Timer.lap queried the system time twice; once to compute the lap
time and once to reset the timer. This can lead to time discrepancies
between actual and computed durations when summing the result of
Timer.lap in a loop. This commit fixes that.

also fix Timer.read to not require a pointer

improve handling of environment variables on Windows
std.os.getenv and std.os.getenvZ have nice compile errors when not linking
libc and using Windows.

std.os.getenvW is provided as a Windows-only API that does not require
an allocator. It uses the Process Environment Block.
std.process.getEnvVarOwned is improved to be a simple wrapper on top of
std.os.getenvW.

std.process.getEnvMap is improved to use the Process Environment Block
rather than calling GetEnvironmentVariableW.

std.zig.system.NativePaths uses process.getEnvVarOwned instead of
std.os.getenvZ, which works on Windows as well as POSIX.

std.os.execvpeZ_expandArg0: fix not restoring argv[0]
This function expands argv[0] into the absolute path resolved with PATH
environment variable before making the execve syscall. However, in case
the execve fails, e.g. with ENOENT, it did not restore argv to how it
was before it was passed in. This resulted in the caller performing an
invalid free.

This commit also adds verbose debug info when native system C compiler
detection fails. See #4521.
