Bowgo Tsai 41d8a576ec <android-base/endian.h>: fix interoperability issue
<winsock2.h> has defined htonl(), ntohl(), htons() and ntohs() with
different return type that cannot be replaced by those macro definitions
in <android-base/endian.h>.

Includes <winsock2.h> first to prevent them from being replaced.
Then defines the macro later so we don't need to call into DLL
when using those functions.

Yurii Zubrytskyi d77c99ebc3 [base] Make MappedFile work with OS file handles
adb uses its own implementation of Windows HANDLE->int mapping,
and it doesn't play well with _get_osfhandle() function used in
MappedFile::FromFd().

This CL adds another function that accepts raw handle, so adb
can pass it directly

+ make constant functions 'const'
+ make the MappedFile movable, as nothing prevents it from being
  one

Colin Cross 888c1b9de5 Fix more endian.h issues
__BIONIC__ is defined in sys/cdefs.h, __GLIBC__ is defined in
features.h (which is included from sys/cdefs.h).  If sys/cdefs.h
was not included before android-base/endian.h it was always falling
back to the Windows definitions.

mingw defines LITTLE_ENDIAN, BIG_ENDIAN and BYTE_ORDER in
sys/params.h, use those definitions to avoid conflicts.

glibc uses different names for letoh*, add compatibily #defines.

Elliott Hughes f86ea02de6 Use as much of the macOS endian support as we can.
Turns out that although there's no <endian.h> or <sys/endian.h>, there
are <machine/endian.h> and <sys/_endian.h>, and they're included by
other system headers such as <dirent.h>.

Reuse the contents of <sys/_endian.h> here for better interop.

Jooyung Han df7d32753e fix: passing ResultError to Error thru operator<<
It is typical to pass error to callers like following;

    if (!result) {
      return Error() << result.error();
    }

To transfer errno(or ResultError#code()), Error defines a specialization
operator<<(const ResultError&).

This change fixes so that ResultError is properly handled

Almost all of the uses of cmsg(3) in our source tree are wrong in at

  - not aligning the cmsg buffer
  - leaking fds if more fds are received than expected
  - blindly dereferencing CMSG_DATA without checking the header
  - using CMSG_SPACE instead of CMSG_LEN for .cmsg_len
  - using CMSG_LEN instead of CMSG_SPACE for .msg_controllen
  - using a length specified in number of fds instead of bytes

Andreas Gampe 2819c0b831 Base: Explicitly set abort message on FATAL
Currently bionic only stores the first invocation of
android_set_abort_message, libbase splits the logging invocations
into discrete lines, and liblog automatically calls bionic when
fatal severity is used. This leads to only the first line of
LOG(FATAL) being stored for tombstoned.

Eagerly set the abort message directly before logging when the
severity is FATAL. This ensures the complete message will be
available.

Elliott Hughes 4679a39610 adb: rationalize fatal/error logging.
Let's use LOG(FATAL)/PLOG(FATAL) for actual fatal stuff.

Add a Windows error(3) and move folks who didn't really mean "abort"
fatal over to it. Also get rid of syntax_error which wasn't adding a
lot of value, and most of the places it was adding "usage: " didn't seem
entirely appropriate anyway.

In particular, we seemed to have confused fastdeploy.cpp into aborting
in most user error cases, and none of the reviewers noticed. Clearly
we'd all lost track of far too many options.

(I've also cleaned up a few random instances of fprintf(3) + exit(2).)

Christopher Ferris eea85c9aab Add Start/Stop/Reset to CapturedStdFd.
Move the fd() function to be private since it should not have been
exposed in the first place.

Fix the way logging_test uses CapturedXXX.

Adding this because the new isolated testing doesn't print errors to
stderr so the ASSERT_ EXPECT_ messages can get swallowed. Also, it's easier
to reuse a CapturedXXX object in a test with these functions.

Test: New unit tests pass.

Josh Gao a3c868879c libbase: add Fdopen that takes a unique_fd.
Using fdopen with unique_fd correctly is more annoying than it should
be, because fdopen doesn't close the file descriptor received upon
failure, which means you have to something like the following:

    unique_fd ufd = ...;
    int fd = ufd.release();
    FILE* file = fdopen(fd, "...");
    if (!file) {
        close(fd);
        return;
    }

Add an android::base::Fdopen that does that dance for you.

   change.
2) ParseUint rejects negative numbers except in the case that the

   that by rejecting any string with a - prefix.
