Comments/document cleanup relative to EVS/FS review (and #1294)

[skliper]

Is your feature request related to a problem? Please describe.
CFE_FS_ReadHeader parameter descriptions out of order:

cFE/modules/core_api/fsw/inc/cfe_fs.h

Lines 60 to 72 in e80aae9

	** \param[in] FileDes File Descriptor obtained from a previous call to #OS_OpenCreate
	** that is associated with the file whose header is to be read.
	**
	** \param[in, out] Hdr Pointer to a variable of type #CFE_FS_Header_t that will be
	** filled with the contents of the Standard cFE File Header. *Hdr is the contents of the
	** Standard cFE File Header for the specified file.
	**
	** \return Execution status, see \ref CFEReturnCodes
	**
	** \sa #CFE_FS_WriteHeader
	**
	******************************************************************************/
	CFE_Status_t CFE_FS_ReadHeader(CFE_FS_Header_t *Hdr, osal_id_t FileDes);

"primary header" not clear in CFE_FS_Header_t description, really it's the size of this header so tools can be agnostic:

cFE/modules/core_api/fsw/inc/cfe_fs_extern_typedefs.h

Line 216 in e80aae9

uint32 Length; /**< \brief Length of primary header */

s/Kog/Log/:

cFE/modules/core_private/fsw/inc/cfe_evs_log_typedef.h

Line 43 in e80aae9

uint16 LogCount; /**< \brief Local Event Kog counter */

Typo, but could also just simplify: Get null terminated name for reporting, example below but in 10 copy/paste locations:

cFE/modules/evs/fsw/src/cfe_evs_task.c

Line 752 in 73c338d

* Althgouh EVS_GetApplicationInfo() does not require a null terminated argument,
