f643b354fe Make the host_init_verifier init.rc parser follow symlinks.
Bazel's intermediates/inputs are symlinks in its execution root, unlike Soong.

e.g.

$ file $(readlink -f out/bazel/output/execroot/__main__/packages/modules/adb/apex/adbd.rc)

6b88d1684c Parser::ParseConfigFile returns Result<void>
ParseApexConfigs() uses Parser::ParseConfigFile() to parse .rc files in
the target apex. ParseConfigFile() returning bool (with logging on
error) doesn't propagate the error message back to the callers
(including apexd or PackageManager).

We'd better to migrate other Parse*() methods of Parser class to return
Result<T>. But this change focuses on plumbing error progagation for
APEX configs.

f1200fb117 Adds an init host lib for use in host_apex_verifier.
Includes extracting the APEX-specific SDK version naming scheme filter
logic so it can be reused when host_apex_verifier looks at rc files
inside the APEX.

85f2bc930a Cleanup some trivial TODOs.
1) There's no reason or way to support boot_clock for waiting for
   property changes, since the underlying futex_wait uses
   CLOCK_MONOTONIC.  We probably wouldn't want boot_clock even if it
   did, since it doesn't make sense to consider the time a device was
   suspending in the timeout for waiting for a property to change.
2) The init tokenizer has been essentially unchanged for a decade,
   there's no motivation to 'fix' it to not require a trailing
   newline.
3) The ueventd TODO regarding moving vendor specific ueventd.rc
   entries out of rootdir has been fixed.

0166fd606d init: fix error messages when an invalid section header is found
If a section header such as 'on' or 'service' has an error with it,
the rest of the commands / options are currently reported as errors
since there is no valid parser object to parse them.  For example,

service !@#$%%^&*() /system/bin/false
    user root
    group blah
    blah blah

Generates:

init: /system/etc/init/bad.rc: 2: invalid service name '!@#$%%^&*()'
init: /system/etc/init/bad.rc: 3: Invalid section keyword found
init: /system/etc/init/bad.rc: 4: Invalid section keyword found
init: /system/etc/init/bad.rc: 5: Invalid section keyword found

This change suppresses the extraneous 'Invalid section keyword found'
messages.

Test: faulty error messages are suppressed.

d72432de93 Don't check permissions bits on init scripts for host_init_verifier
Also get rid of the copy in parser.  There's no incentive to switch to
a tokenizer that doesn't modify the input, nor is there a reason to
waste cycles making a copy of every init script as its processed.

individual line callbacks used for ueventd correctly.  This change
fixes that.

194b5d1da9 init: handle properties and imports for host init verifier
Allow specifying properties on the command line when running host init

directory of Android builds.

62ca663475 init: introduce Result<T> for return values and error handling
init tries to propagate error information up to build context before
logging errors.  This is a good thing, however too often init has the
overly verbose paradigm for error handling, below:

bool CalculateResult(const T& input, U* output, std::string* err)

bool CalculateAndUseResult(const T& input, std::string* err) {
  U output;
  std::string calculate_result_err;
  if (!CalculateResult(input, &output, &calculate_result_err)) {
    *err = "CalculateResult " + input + " failed: " +
      calculate_result_err;
      return false;
  }
  UseResult(output);
  return true;
}

Even more common are functions that return only true/false but also
require passing a std::string* err in order to see the error message.

This change introduces a Result<T> that is use to either hold a
successful return value of type T or to hold an error message as a
std::string.  If the functional only returns success or a failure with
an error message, Result<Success> may be used.  The classes Error and
ErrnoError are used to indicate a failed Result<T>.

A successful Result<T> is constructed implicitly from any type that
can be implicitly converted to T or from the constructor arguments for
T.  This allows you to return a type T directly from a function that
returns Result<T>.

Error and ErrnoError are used to construct a Result<T> has
failed. Each of these classes take an ostream as an input and are
implicitly cast to a Result<T> containing that failure.  ErrnoError()
additionally appends ": " + strerror(errno) to the end of  the failure
string to aid in interacting with C APIs.

The end result is that the above code snippet is turned into the much
clearer example below:

Result<U> CalculateResult(const T& input);

Result<Success> CalculateAndUseResult(const T& input) {
  auto output = CalculateResult(input);
  if (!output) {
    return Error() << "CalculateResult " << input << " failed: "
                   << output.error();
  }
  UseResult(*output);
  return Success();
}

This change also makes this conversion for some of the util.cpp
functions that used the old paradigm.
